  • Eulerian–Lagrangian and thin film modeling of drug delivery under physiologically varying breathing in a realistic lung model
    Sameer Kumar Verma, Saurabh Bhardwaj, Kishore Singh Patel, B. Kiran Naik
    Physics of Fluids, 2026
    This work presents a computational approach to investigate antiviral aerosol deposition in anatomically realistic human airways under various physiological inhalation conditions. Antiviral drugs are represented as fine droplets that form a thin coating on airway surfaces, primarily targeting early infection sites. The suggested method combines an Eulerian–Lagrangian discrete phase model (DPM) to track droplet motion and an Eulerian wall film (EWF) model to mimic the evolution of deposited liquid films. This combination effectively addresses the shortcomings of previous studies that employed DPM exclusively, which ignored the post-deposition redistribution dynamics of liquid drugs on airway surfaces. To the best of our knowledge, this is the first study to integrate a DPM–EWF framework within a realistic airway model under both healthy and disease-specific inhalation conditions to predict drug delivery. The study assesses airflow parameters, film thickness, deposition efficiency, and surface area coverage for aerosol particles from 1 to 10 μm. Results reveal that distressed breathing patterns of chronic obstructive pulmonary disease patients significantly alter the deposition preferences between the upper (∼5.28%) and lower lobes (∼2.52%) compared to the equivalent ideal (upper: ∼3.31%, lower: ∼4.32%) and realistic healthy (upper: ∼3.80%, lower: ∼6.79%) inhalations. Moreover, the distressed breathing also limits the drug penetration into deeper generations, as the highest surface coverage is observed at the carinal region rather than the usual left lower lobe found in ideal and realistic healthy breathing cases. Such deposition contrasts highlight the importance of optimizing inhalation therapy and device designs for individuals with obstructive airway diseases.

    Water Energy Nexus, 2025
    • Developed FDM based thermal model to assess sustainable SCHW performance. • Conducted thorough parametric and performance analyses on novel SCHW system. • Performed feasibility analysis of SCHW system for various climatic regions in India. • SCHW is effective in hot and dry region with a 0.78 L/h-m 2 water extraction rate. • SCHW significantly improves sustainable water management in scarce water areas. This research presents a sustainable humidification-condensation system for freshwater extraction from wastewater, utilizing an evacuated U-tube solar collector powered by solar energy. The efficiency of the newly proposed system is evaluated by developing a thermal model and solving it through a finite difference approach. The humidifier and condenser module were validated individually against experimental data, and the maximum possible error is estimated at ±12 % and ±10 %, respectively. The developed thermal model shows strong predictive capability for the humidification-condensation based wastewater recovery system, with R 2 values of 0.9987 (energy exchange), 0.9944 (water extraction rate), 0.9850 (condensate), 0.9492 (humidified air), 0.9793 (humidity ratio), and 0.9559 (cooling water temperature), all within acceptable error margins. Analysis of various parameters alongside the performance evaluation of the proposed novel system was conducted using the developed model. The parametric analysis revealed that the solar exit water temperature significantly impacts the performance of the novel systems. Moreover, performance assessments show that the system benefits from lower water temperatures at sources like dams, rivers, or seawater, as well as from a more effective water condenser and a higher flow rate. Further analysis of condenser effectiveness, fluid flow ratio, and cooling water temperature indicates maximum achievable water condenser energy exchange (WCEE) and water extraction rate (WER) of 1.37 kW/m 2 and 1.445 L/h-m 2 , respectively. The evaluation determined that the proposed sustainable system is ideally suited for hot and dry climates, with a potential WCEE and WER of up to 0.8 kW/m 2 and 0.78 L/h-m 2 based on the system’s specifications and operating parameters. Additionally, WER increased by 71 % and 62 % with an increase in solar energy input at given wastewater temperature and air flow rate in the humidifier. An assessment of the correlation matrix revealed that the specific humidity of humidified air strongly influences moisture energy exchange (correlation ( r ) = 0.92), while air inlet temperature is the key factor affecting WCEE ( r = 0.96) and WER ( r = 0.98), indicating its critical role in system performance for hot and dry regions. The current study provides insights into solar potential hotspots for wastewater recovery across different climatic conditions.

    Sameer Kumar Verma, Kishore Singh Patel, B. Kiran Naik
    Molecular Pharmaceutics, 2024
    The current study explores the effectiveness of drug particle deposition into human respiratory airways to cure various pulmonary-bound ailments. It has been assumed that drug solutions are inhaled in the form of tiny droplets or mist, which after striking create a thin layer along the inner surface of airways where the virus initially resides to infect the human body. A coupled Eulerian wall film (EWF) and discrete phase model (DPM) based simulation approach is used to capture these dynamics. Here, the Lagrangian DPM technique tracks the dynamics of tiny droplets, while the liquid layer formation after striking is captured using the Eulerian thin film approximations or the EWF model. Previous studies in this field primarily employed only the DPM method, which is inadequate to predict the poststriking dynamics of drug layer deposition and their spread to neutralize the respiratory virus. The drug delivery effectiveness is characterized by three different particle sizes, 1, 5, and 10 μm at the inhalation rates of 15, 30, and 60 L per minute (LPM). It has been found that the size of the drug particles significantly influences drug delivery effectiveness. The film thickness increases monotonically with particle sizes and inhalation rates. However, this increase in averaged film thickness is prominent in the range 5 to 10 μm (≈60%) compared to 1 to 5 μm (≈10%) droplet sizes at generation level 4 (G4). The other deposition parameters, e.g., deposition fraction, deposition density, and area coverage) roughly show similar behavior with the increase in droplet sizes. Therefore, it is recommended to vary the droplet sizes between 5 and 10 μm for better deposition effectiveness. The sizes of more than 10 μm mostly stuck into the oral cavity and cannot reach the targeted generations. In contrast, less than 5 μm may reach much deeper generations than the targeted one.
  • Sustainable wastewater recovery system employing geothermal energy – Performance and feasibility study
    Manish Sonkar, Shubham Kumar Pati, B. Kiran Naik, Kishore Singh Patel
    Desalination and Water Treatment, 2024
    In this study, a sustainable wastewater recovery system employing geothermal energy has been proposed. The efficiency of the suggested sustainable system has been simulated using heat transfer. Then, component-wise validation has been carried out with the existing data available in the literature wherever applicable and estimated an error of ± 8 %. The proposed sustainable system’s parametric and performance analyses have employed the developed vapor. From the parametric study, it is observed that hot spring temperatures have a significant influence on sustainable systems. Further, through performance investigation, it is understood that low dam/river/sea water temperatures and enhancing the water condenser effectiveness and flow rate ratio simultaneously improve the system performance. For different climatic regions of India, explored the feasible geothermal hotspots near dams/rivers/seawater and analyzed that among the hot and dry, hot and humid, composite and cold regions, the proposed sustainable system is best suitable at a composite region with a maximum possible water extraction/freshwater generation rate of 0.78 L/h for the given specifications and operating range. Moreover, it is assessed that hot spring temperature is the deciding factor for sustainable system performance in different climatic regions. Further, the current study can be used as a reference for understanding the phenomenon of potential geothermal hotspots for wastewater recovery in various climatic areas
