Paper Title :
Effect of Nozzle to Plate Distance on Local Heat Transfer Distribution by Incompressible Chevron Jet using CFD

Author :Harpreet Singh, Sunil Chandel

Article Citation :Harpreet Singh ,Sunil Chandel , (2018 ) " Effect of Nozzle to Plate Distance on Local Heat Transfer Distribution by Incompressible Chevron Jet using CFD " , International Journal of Mechanical and Production Engineering (IJMPE) , pp. 61-64, Volume-6,Issue-6

Abstract : In this paper, numerical simulation was performed to analyze the effect of nozzle to plate distance on heat transfer performance of an incompressible hot jet by a chevron nozzle on a flat surface. Influence is studied at the nozzle to plate distance (z/d) 1, 2, 4, 6, 8 and 10 for Reynolds number of 28,000. Numerical analysis has been done by solving conservation equations of momentum, mass and energy with two equations based RNG k- ε turbulence model and Energy model to determine the local distribution of Nusselt number on the plate. A change in Nusselt number distribution is observed, for lower nozzle to plate distance (z\d ≥ 4) secondary peak in the Nusselt number is present. From nozzle to plate distance (z/d ≤ 6), the Nusselt number decreases gradually from the stagnation point in the radial direction. Keywords - Chevron Nozzle, Nusselt Number, Heat Transfer, Computational Fluid Dynamics
