Heat transfer enhancement plays an important role in areas, such as
electronics cooling, compact heat exchangers, power plants, gas turbine
airfoil cooling, etc. Modern high-performance gas turbine engines
operate at high entry gas temperature, well above the allowable metal
temperature. Therefore, highly efficient cooling technologies (film
cooling, impingement cooling, and internal cooling) are required for
vanes and blades of advanced gas turbines. In this book, the authors are
shows the effect of incorporating ribs in the straight channels with
variable aspect ratio. The effect of Reynolds number on fluid flow and
heat transfer is also investigated.
