Title

COMPUTATIONAL FLUID DYNAMICS ANALYSIS AND OPTIMIZATION OF DIFFERENT PARAMETERS OF HEAT EXCHANGER USED IN AERO ENGINES

Abstract

In order to maintain the temperature of the fin-tube heat exchangers, this will show potential applications in aero engines for their high efficiency and security as compared with other types of heat exchangers used in different areas, heat exchangers used in aero engines are more compact and it is at much higher temperatures and larger temperature differences. The change in temperature over the increase in heat exchanger depth and the temperature gradient in the near wall region are more conspicuous, it may have difference of several hundred degrees. After using the heat exchanger large temperature change means significant increase in fluid properties variation, which must be considered when evaluating the exchanger performance. Inside the aero engine air coming from compressor is often used for turbine airfoil cooling in aero engines. Here in this work tube type heat exchangers are selected for the present research it has a plain finned tube configuration. Hot air coming from compressor flows across the tube bank while here in this analysis cold fluid that may be fuel oil flows inside the tubes. The two configurations have the same tube geometry which is a staggered tube arrangement. it numerically investigates the heat transfer and pressure variation characteristics of such exchangers with consideration of the air property variability which caused the air temperature changes.
