Thermal Performance Analysis of a Direct-Heated Recompression Supercritical Carbon Dioxide Brayton Cycle Using Solar Concentrators

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

Simulated thermal performance of a solar heated floor

A low cost, simple solar heating system consisting of an active collector with an In-Floor Heat Distribution and Storage (IFHDS) system was developed in response to the energy crisis of the 1970s. A two-dimensional finite difference model was developed and used to simulate the performance of IFHDS system cross-sections. Simulation runs were conducted with a steady-periodic model for the tempera...

Effective terminal sterilization using supercritical carbon dioxide.

Gentle alternatives to existing sterilization methods are called for by rapid advances in biomedical technologies. Supercritical fluid technologies have found applications in a wide range of areas and have been explored for use in the inactivation of medical contaminants. In particular, supercritical CO(2) is appealing for sterilization due to the ease at which the supercritical state is attain...

Analysis of a High Temperature Supercritical Brayton Cycle for Space Exploration

This paper provides a preliminary analysis of the supercritical Brayton cycle, a power generation system for space exploration. Supercritical working fluids increase efficiency due to increased compressibility at the critical point but have not been investigated at the high temperatures necessary for space power generation. Through computer simulation, the viability of the supercritical Brayton...
