Thermodynamic Performance of Boehmite Alumina Nanoparticle Shapes in the Counterflow Double Pipe Heat Exchanger

This work compares a theoretical model with consolidated numerical related to the thermodynamic performance of boehmite alumina nanoparticles in different formats counterflow double pipe heat exchanger. The shapes non-spherical under analysis are platelets, blades, cylindrical, and bricks. second law thermodynamics is applied determine Nusselt number, pressure drop, thermal efficiency, viscous irreversibilities, Bejan out temperature hot fluid. entropy generation rates associated field flow graphical determined. uses k-ε turbulence model, which requires empirical factors simulate turbulent viscosity rate kinetic energy. Compatibility between models was demonstrated. It shown that maximum absolute error quantities transfer rate, drop for established specific conditions less than 12.5 %.
