The printed circuit heat exchanger (PCHE) plays a vital role in the supercritical CO2 cooling system for hypersonic aircraft, which significantly affects efficiency and stability of system. In this study, novel structure is proposed to improve overall performance airfoil fin PCHE. RP-3 aviation kerosene SCO2 are used as working fluids study thermal-hydraulic enhancement mechanism. results indic...

Mini-channel heatsinks have proven useful in removing high heat fluxes from microelectronic devices. However, further miniaturization of electronic devices requires significant enhancement the mini-channel heatsinks’ thermohydraulic characteristics, which depend greatly on coolant and geometrical configuration channel. Therefore, current study explores potential using different coolants (water,...

Excessive heat losses and water consumption in cooling units are significant constraints restricting the application circumstances performances for SCO2 Brayton cycle, exchange capacity precooler (PRC) is typically 1.5 times that of power generation. Therefore, this research offers a high-integrated combined power/cooling system which two waste exchangers (WHEs) rectifier (RET) used instead PRC...

sCO2 power cycle is the most investigated and promising technology for replacing conventional steam in CSP plants. Nevertheless, efficiency of strongly penalized by high ambient temperatures which are typical favourable locations. This paper focuses on a new working fluid cycles consists CO2 blended with C6F6. The addition C6F6 increases critical temperature allowing condensing up to 45 °C. cal...
