Supercritical Carbon Dioxide Power Cycles


I have been exploring the design space of a Supercritical Carbon Dioxide Power Cycle using a custom developed variable property heat engine cycle analysis code. So far one paper has been written and two web based tools have been developed.

Mapping the Design Space of a Recuperated, Recompression, Precompression Supercritical Carbon Dioxide Power Cycle with Intercooling, Improved Regeneration, and Reheat:

Supercritical Carbon Dioxide Power Cycle Design Explorer: This tool displays the current results of the design space exploration with parameters which can be user selected to be either fixed or optimized. The results are presented in the form of a contour plot with selectable horizontal and vertical axes and contour level variables showing the sensitivity of two or three parameters to the cycle efficiency, a line plot with selectable horizontal and vertical axes variables showing the sensitivity of one or two parameters to the cycle efficiency, and a cycle plot with selectable horizontal and vertical axes and contour level variables showing the state variables of the fluid at the inlet, outlet, and within key mechanical components in the cycle.

Real Fluid Heat Exchanger Solver: This tool displays the temperature difference and heat capacities in a heat exchanger using a simple heat exchanger model, while still accounting for real fluid properties which vary radically with temperature and pressure. The heat exchanger model used is that which is incorporated into variable property heat engine cycle analysis code. Heated side mass fraction, pressure drop, and cooled and heated side inlet conditions are user selectable. This tool aims to visually demonstrate the complex operation of heat exchangers with variable fluid properties.

Below are samples figures from these tools.
