    A fundamental question in the design of finned heat exchanger surfaces and electronics packages is how to determine the spacing between heat generating plates in a stack of fixed volume. When the stack peak temperature (hot spot) is fixed, the optimal plate-to-plate spacing corresponds to the maximum heat transfer rate from the entire stack to the ambient fluid. The optimal spacing problem was solved for configurations where the stack is cooled by natural convection. Stacks cooled by forced convection were optimized only in cases where the flow is laminar. The objective of this note is to report the optimal plate-to-plate spacing when the stack is cooled by turbulent forced convection
