Summary

It is shown that the best way of positioning the plates relative to one another is by spacing them equidistantly. When the overall dimensions of the stack are specified, there is an optimal number of plates for minimum thermal resistance. The optimal number and minimum resistance are anticipated theoretically and correlated into compact formulas that agree with numerical and experimental results in the Reynolds number range 100-10,000. Finally, it is shown that a stack with more plates than the optimal number can be modelled more expediently as a porous block immersed in a free stream.
