Abstract
Two nondimensional parameters are used to describe relative sizes of regenerative heat exchangers, regardless of type or surface characteristics. These are:
and
They are related to gas turbine cycle factors to demonstrate that, for fixed bsfc goals, heat exchanger matrix sizes are very sensitive to turbine inlet temperature, pressure ratio, and flow path efficiency. Methods for optimizing engine cycles to minimize the sizing factors are described. A general trend toward higher pressure ratios in future recuperative gas turbines is indicated.
