Abstract EN
A computational study on conjugate heat transfer is carried out to present the behavior of nondimensional temperature and heat transfer coefficient of a Nozzle Guide Vane (NGV) leading edge.
Reynolds number of both mainstream flow and coolant impinging jets are varied.
The NGV has five rows of film cooling holes arranged in shower head manner and four rows of impingement holes arranged in staggered manner.
The results are presented by considering materials of different thermal conductivity.
The results show that the mainstream flow affects the temperature distribution on the interior side of the vane leading edge for high conductivity material whereas it has negligible effects for low conductivity material.
The effect of changing blowing ratio on internal heat transfer coefficient and internal surface temperature is also presented.
