This case study presents the design of a reverse Brayton cryocooler. The Component Library is used to simulate the recuperative heat exchanger and design the turbomachines. The Balje curves are used to determine the best on-design sizing for the turbine and compressor (speed and size). Finally, a parametric study is carried out to optimize the performance of the system while simultaneously maximizing the size of the turbomachinery. The result is presented in two, overlaid contour plots.
