RESTRUCTURE THERMAL MANAGEMENT: ENHANCED PERFORMANCE OF CLOSED LOOP PULSATING HEAT PIPE (CLPHP) WITH SYNTHESIZED REDUCED GRAPHENE NANOFLUID (rGN) FOR ADVANCED ELECTRONIC AND 3D PRINTER EXTRUDER COOLING Aruna Veerasamy, Anish M., Jayaprakash V. ASME International Mechanical Engineering Congress and Exposition Proceedings Imece, 2025 Optimal performance and efficiency in modern electronics as well as in additive manufacturing require strict attention to thermal management. This research evaluates the thermal performance of Closed Loop Pulsating Heat Pipes (CLPHP) with a prototype design using synthesized reduced graphene nanofluid (rGN) as a working fluid. The prototype CLPHP was subjected to various heat loads testing with rGN at two concentrations (0.005 wt% and 0.01 wt%) to mimic practical scenarios. The synthesis for the rGN was processed through two-step method where stability and some thermal properties shall be checked for. Experimental results indicated that rGN enhanced CLPHPs by reducing thermal resistance up to 25% and improving thermal conductivity up to 80-90% to other fluids like DI water. Due to these advantages, rGN based CLPHPs could be used in applications that require hard precision cooling such as 3D printers extruders and electronic devices. This work supports the claim that graphene nanofluids have potential in heightening heat pipe technologies that need imp[lamentation in advanced systems for thermal management.
FUTURE OF LIGHTWEIGHT DESIGN: ADVANCEMENTS IN LATTICE STRUCTURE THROUGH ADDITIVE MANUFACTURING AND SLS 3D PRINTING TECHNOLOGY Aruna Veerasamy, Kanimozhi Balakrishnan, Madhanagopal Manoharan ASME International Mechanical Engineering Congress and Exposition Proceedings Imece, 2025 In the manufacturing industries, there is a demand for lightweight, high performance, which may lead to the application of lattice structures as transformative solution in Additive Manufacturing (AM) or 3D printing. This is based on the inherent excellent strength weight ratios, better energy absorption capacity, and tailorable geometries for aerospace, automotive, and biomedical applications. The current research applies an experimental realization of optimized lattice models with the following materials: Nylon 12, Nylon 12 with glass fiber, Poly Propylene, and Nylon 12 with carbon fiber material. Selective Laser Sintering (SLS) type 3D printing technology is used for manufacturing products in this study. Lattice structure were designed and tested using tensile and compression tests. Materials were characterized by FESEM, XPS, Raman spectroscopy, and shore D hardness analysis after the SLS process. Meanwhile, CATIA 3D Experience software is used to design the ASTM and lattice model for this study. This work shows the potential of integrating advanced computational tools, innovative lattice concepts, and optimized AM processes to overcome challenges related to material limitations, scalability, and sustainability. These designs and materials are validated for their efficiency, durability and functionality to enhance performance. These findings are the key for the development of next generation lightweight components with enhanced performance and broader engineering applications.
Statistical optimization of Closed Loop Pulsating Heat Pipe parameters with R-410a and nanorefrigerant in air conditioning applications Aruna Veerasamy, Kanimozhi Balakrishnan, Sirajunnisa Abdul Razack Energy Sources Part A Recovery Utilization and Environmental Effects, 2025 The present investigation is an attempt to study the effect of refrigerant with nanoparticles against conventional refrigerant in closed loop pulsating heat pipe (CLPHP). Here, a customized CLPHP was used in this study and nanorefrigerant was prepared using R-410a with graphene nanoparticles in distilled water as the novel working fluid. The process parameters for CLPHP with both refrigerants, optimized using the statistical tool Response Surface Methodology based on central composite design, were inclination angle (θ°) ranging between 85 and 95, and power (W) ranging between 90 and 110. In this study, thermal conductivity (Rth), thermal resistance (k) and temperature difference (Δ T) between evaporator and condensor were analyzed. The optimized parameters for standard refrigerant were found to be: inclination angle 92° and power 104 W whereas for nanorefrigerant the parameters were 88° and 102 W. The yields in terms of Rth, k and T for refrigerant were 0.015°C/W, 6284.33 W/mK and 10°C and those for nanorefrigerant were 0.0025°C/W, 32376.72 W/mK and 18°C. This investigation revealed that the R2 values were approximately 100% in both cases illustrating that the statistical evaluation was true to the experimental model and befitting the same. The complete results exhibited that in both cases thermal conductivity increased while thermal resistance decreased. Also, differences in temperature between evaporator and condensor was larger in CLPHP with nanorefrigerant while it was lower in CLPHP with R-410 alone. Hence, the overall study suggested that the efficacy of R-410a with graphene nanoparticles was 80.05% better than that of lone R-410a in CLPHP. In conclusion, this experiment evinced the positive utilization of nanorefrigerant as working fluid in CLPHP for air conditioning applications.
Experimental study of heat pipes for battery cooling technology in EVs Aruna Veerasamy, Godwin Antony Zeitschrift Fur Physikalische Chemie, 2024 The modern world is moving towards electric vehicles (EV) due to the increment in greenhouse gas (GHG) emissions, global warming, and the lack of fossil fuels. EVs can overcome these issues by using batteries instead of fuel. But increasing and maintaining the batteries is a major challenge in EVs because of the large heat emissions from the batteries. In order to overcome these issues and increase the performance of the batteries, a heat pipe (HP) is attached to the passive cooling system. This study aims to improve the performance of batteries and the thermal conductivity of HP with a combination of refrigerant and nanofluid (nanorefrigerant) as working fluids. Copper HP with R-134a or SWCNT is selected for this study. The thermal resistance and thermal conductivity of HP with R-134a and SWCNT were observed for several heat conditions. From the study, it was well observed that changing the working fluid inside the HP affects the thermal performance and the cooling capacity of batteries. Fixing an HP to a battery would decrease the battery’s temperature effectively. Furthermore, increasing the heat power in an evaporator section decreases the thermal resistance and enhances thermal conductivity with the shortest time limit because of Brownian motion.

Efficiency improvement of heat pipe by using graphene nanofluids with different concentrations Aruna Veerasamy, Kanimozhi Balakrishnan, Teja Surya, Zaheer Abbas Thermal Science, 2020 In the present study thermal performance of heat pipe were validated experimentally. Circular, auxiliary grooved heat pipe were charged with graphene nanofluid with different concentrations (0.6%, 0.75%), orientation, and flow rate are fixed as 90° and 100 mL per minute. All the experimental results are validated and compared to base fluid (deionized water). From the experimental results, in-creasing nanofluid concentrations increases thermal performance and decreases thermal resistance. Although the wall temperature of heat pipe higher with graphene/water nanofluid than base fluid. Thus, graphene nanoparticles are suitable for heat pipe to increase their performance and capillary action.
