PERFORMANCE EVALUATION OF BIOMASS DRYER WITH WASTE HEAT RECOVERY UNIT FOR DRYING PIRANDAI П. Муруган, С. Дханушкоді, K. Судхакар, П. Балу, Ю. Гончаренко Vidnovluvana Energetika, 2026 This study presents the performance evaluation of a biomass dryer integrated with a waste heat recovery (WHR) unit for drying Pirandai (Cissus quadrangularis), a medicinally valuable plant widely used in nutraceutical and pharmaceutical applications. The dryer was designed to operate with locally available biomass as the primary energy source, while the waste heat recovery system was incorporated to enhance thermal efficiency and reduce overall energy consumption. Experimental trials were conducted to assess drying rate, moisture reduction, thermal efficiency, and specific energy consumption under varying operating conditions. The results indicated that the integration of WHR significantly improved the drying performance, with an average increase in thermal efficiency of 18–22% compared to conventional biomass drying systems. The moisture content of Pirandai was successfully reduced from an initial value of 75% (wet basis) to a safe storage level of 10% within 6 hours of drying. The specific energy consumption was reduced by approximately 20–25 %, highlighting the economic and environmental advantages of the system. Overall, the study demonstrates that biomass dryers coupled with waste heat recovery units provide a sustainable, cost-effective, and energy-efficient solution for drying medicinal plants such as Pirandai, contributing to value addition and post-harvest preservation.
Factorial analysis of lignocellulosic content influence on the permittivity of coconut-shell epoxy dielectric composites K. B. Mekha, Nur Sofia Idayu Didik Aprianto, K. Sudhakar, Norazwina Zainol, Nurulfadzilah Hasan, et al. Journal of King Saud University Engineering Sciences, 2026 The development of sustainable dielectric materials is crucial for advancing next-generation electronic and energy storage systems. This study investigates the dielectric behavior of coconut-shell-based epoxy composites and evaluates the influence of processing parameters using a two-level factorial design (TLFD) coupled with two-level factorial analysis (TLFA). The effects of filler loading, particle size, and curing condition (non-heated and heated) on lignocellulosic content and the real part of permittivity (ε′) were systematically examined at 5 GHz using a vector network analyzer. At a 40 wt.% filler content, the measured lignocellulosic content reached 58.7% (Kurschner-Hanack), with permittivity values ranging from 3.74 to 4.11. Statistical analysis identified the curing condition as the most significant factor affecting ε′, followed by filler loading and particle size. The novelty of this study lies in applying TLFD and TLFA to quantitatively evaluate how lignocellulosic content influences GHz-range permittivity specifically in coconut-shell-based dielectric composites, a compositional factor that earlier coconut-shell studies have not explicitly examined. This approach demonstrates how statistical modeling, supported by ANOVA, can bridge the relationship between material composition and electromagnetic performance in GHz dielectric composites. The findings establish a systematic framework for optimizing bio-based dielectric materials and demonstrate the potential of coconut-shell-derived composites for sustainable electronic applications.
PERFORMANCE ENHANCEMENT OF FLAT PLATE SOLAR PVT COLLECTOR USING ZN-ZNO/WATER HYBRID NANOFLUID K. Сактивел, С. Дханушкоді, K. Судхакар, П. Балу, В. Іванчук Vidnovluvana Energetika, 2025 Providing an analytical examination of the solar flat plate collector (SFPC) is the goal of this work. Using Zn/water, ZnO/water nanofluids, and Zn-ZnO/water hybrid nanofluid. This study compares various mass flow rates and concentrations of nanoparticles. Heat transfer, energy and exergy efficiency, and pressure drop characteristics of SFPC operation on these nanofluids are investigated. The addition of Zn/water nanofluid 16.71%, ZnO/water nanofluid 16.36%, and Zn-ZnO/water hybrid naofluid 18.52% nanoparticles enhances the working fluid's thermal conductivity. Gain in heat is improved with use of Nanofluids Zn/water nanofluid 1.02%, ZnO/water nanofluid 0.90%, Zn-ZnO/water hybrid nanofluid 2.15%. Efficiency improvements observed in SFPC Zn/water nanofluid: 0.93%, ZnO/water nanofluid 1.05%, Zn-ZnO/water hybrid nanofluid: 2.23%. The increase in pumping power required for the nanofluids: Zn/water nanofluid 3.08%, ZnO/water nanofluid 2.38%, Zn-ZnO/water hybrid nanofluid: 2.918%. Improvements in energy efficiency as per exergy analysis: Zn/water nanofluid 2.32%, ZnO/water nanofluid 2.18%, Zn-ZnO/water hybrid nanofluid 2.60%. In solar flat plate collectors, hybrid nanofluid Zn-ZnO/water significantly improves efficiency. The hybrid nanofluid exhibits the highest thermal conductivity and the most substantial improvement in collector efficiency and usable heat gain among the tested fluids. Additionally, despite a slight increase in pumping power requirements, the overall energy and exergy performance enhancements make hybrid nanofluids suitable for SFPC applications. These findings suggest that integrating hybrid nanofluids in SFPCs can lead to more efficient solar energy systems, potentially contributing to better energy management and sustainability. Further research could explore optimizing nanoparticle concentration and flow rates to maximize these benefits while managing pumping power requirements.
