In the present investigation, eight varying concentrations of Aluminum Oxide, Titanium Dioxide, Copper Oxide, Silicon Dioxide and Zinc Oxide nanoparticles, and EG20 (mixture of ethylene glycol 20% wt. and water), water as base fluids are considered. By considering the single-phase model, numerical computation is performed using ANSYS Fluent software. To examine the validity, results are compared with previous experimental and numerical research data. Further, different heat transfer parameters are presented and analyzed. From this analysis, it was noted that with the addition of nanoparticles there are sharp decrements in local thermal resistance and increment in local heat transfer coefficient compared to base fluid. There is a large improvement in heat transfer parameters is noticed in the case of CuO nano...

In the present investigation water, ethylene glycol and a mixture of ethylene glycol (20%wt) and water are considered as base fluids with varying concentration of five different nanoparticles includingAl2O3, TiO2, CuO, SiO2 and ZnO. Numerical computations are performed using ANSYS Fluent software by considering the single phase model and results are validated with available experimental and numerical data. Further parameters like thermal resistance, pumping power, local heat transfer coefficient and temperature variation of IC chip are presented and analysed. It was noted that with addition of nanoparticles there is sharp increment in local heat transfer coefficient and decrements in local thermal resistance compared to base fluid but at same time viscosity of fluid increases that provide more drag or pressure drop w...

Present work deals with the thermodynamic analysis of the metabolic process of humans and establishes the relation for entropy generation. Further, this entropy generation is linked with the thermodynamics life cycle assessment of humans. Data used in this work is provided by the National sample survey office (NSSO), Government of India. Entropy generation is determined on the bases of per kg of carbohydrate, palmitic acid and 20 amino acids. Finally, the life span of humans has been determined on the grounds of the entropy generation. Entropy generated by Haryana people is maximum in all states, and Tamilnadu people have the minimum among all the states. Total entropy production for Haryana is 23.59 kJ/K-kg-food and for Tamilnadu 19.71 kJ/K-kg-food. People living in Haryana has a life span of 66 years, and Tamilnadu people have a life span of 79 years. The life span for other states ranging in 66-79 years. Variation of ±3% is recorded in the life span of people when compared with the NITI Aayog report. There is a minor difference of 1.22 years in case of life expectancy of Kerla when compared to the NITI Aayog report. In current research work effect of water and air, inhalation is not considered. So one can think these parameters and analyze the variation of the result.

These are unique in every human being and obtained from different body parts like skull, heart, kidney etc. these biological materials may be classified as coded organic material, anonymized organic material and mysterious organic material. Human organic materials are very useful in diagnostic, research, education and health related issue. But there are various concerns which are associated with human organic material, ethical issues are always raised by society and storage and disposal of organic material is also difficult.
