Polytropic equation
WebNov 25, 2024 · The polytropic Euler equations are a simplified version of the compressible Euler equations which explicitly conserves the mass and momenta. In the equation of state for polytropic fluids the pressure depends solely on the fluid density and the total energy conservation law becomes redundant [ 10 ]. WebCombining this result with the ideal gas equation of state T 2 T 1 = v 1 v 2 k−1 = P 2 P 1 (k−1)/k The isentropic process is a special case of a more general process known as a polytropic process where → Pvn = constant and n is any number. Special Cases n =1 Pv= RT = constant ⇒ isothermal process n =0 Pv0 = constant = P ⇒ isobaric ...

WebMay 23, 2024 · This equation shows that the polytropic work (Wp) is only dependent upon the compressor suction and discharge values of pressure (P), temperature (T), specific volume (v), and the gas molecular weight (MW). The average polytropic exponent, n, included in these relations is also derived from these parameters.
WebWhat is the meaning of polytropic index? The polytropic index is that defined via a polytropic equation of state of the form P1+1/n, where P is pressure, is density, and n is the polytropic index. There is a relationship between the polytropic index and the adiabatic index. The latter is defined through PV=constant.
