Steady state and transient analysis of compact plate-fin heat exchanger fins for generation of design data using CFD

Ranganayakulu Chennu

The purpose of this paper is to carry out numerical modeling of single-blow transient analysis using FLUENT porous media model for estimation of heat transfer and pressure drop…

Investigation of thermal damage of tissues embedded with large blood vessels during plasmonic photo-thermal heating (PPTH)

Anup Paul, Arunn Narasimhan, Sarit Kumar Das

The large blood vessels (LBV) would act as a heat sink and hence play a significant role during photo-thermal therapy. Gold nanoshell was considered as a high-heat absorbing agent…

Effects of ligaments shape on radiative heat transfer in metal foams

Salvatore Cunsolo, Dominique Baillis, Nicola Bianco, Vincenzo Naso, Maria Oliviero

The purpose of this paper is to investigate the impact of ligament shape on radiative behavior, with a specific focus on the inter-dependence among porosity, ligament shape and…
