Abstract

ABSTRACT Numerical investigations in the channel with lower and upper corrugated plate under constant heat flux conditions using nonafluids are carried out. CFD model by a finite volume method FVM with the structured uniform grid system is employed to solve the continuity momentum and energy equations. The flow and heat transfer developments are simulated by using the k-26949 standard turbulent model. The corrugated plates with corrugated tilt angle of 60 are tested with the height of the channel of 17.5 mm and wavy height of 2.5 mm. The model was simulated for the Reynolds number in the range of 5000 -20000. Studies are carried out for 2612310SiO 26123112 nanoparticles with different volume fractions in the range of 0-4 and different nanoparticles diameters in the range of 20-80 nm. The results show that the heat transfer enhancement increased by using nonafluids as working fluid. The nanofluid with 2612310SiO 26123112 has the highest Nusselt number compared with base fluid . It is found that the average Nusselt number increased with the increase of volume fraction of the nanoparticles and Reynolds number accompanied by a slight increase in pressure drop. It is found that with the decrease of nanoparticle diameter the Nusselt number increased for 2612310SiO 26123112 - water. Therefore the nonafluids has a significant effect on the performance of heat transfer in the corrugated plate.
