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.
