Rayleigh temperature

WebThe Rayleigh flow model begins with a differential equation that relates the change in Mach number with the change in stagnation temperature, T 0. The differential equation is shown below. Solving the differential equation leads to the relation shown below, where T 0 * is the stagnation temperature at the throat location of the duct which is required for thermally … WebTelephone : +48 22 290 27 26 www.rayleigh.pl +44 (0) 1245 428 500 We are manufacturers and stockists of an extensive range of energy monitoring products including current transformers, kilowatt hour (kWh) meters, multifunction power monitors, measuring transducers, data loggers, communication interfaces and software.
