WebIn a polytropic process, the compression or expansion process takes place in small steps (infinitesimally small steps). Calculating the work for the polytropic process involves the summation of the work for each step. To calculate the work for each infinitesimal step, we use the isentropic analysis discussed in Section 2.8.2. Web3 that involves the thermal pressure P, the temperature T, and the density n of the plasma. The polytropic expression for the logarithms of the thermal variables becomes linear and allows a straightforward estimation of the polytropic index γ by examining datasets of log(T) vs. log(n). Variations in γ among ICME structures is an indicative of heating processes.
WebDec 31, 2024 · The equation for a polytropic process is generally written as p V n = C Where n is called the polytropic index (not to be confused with n being the number of moles of a gas) and C is a constant. The equation can be used to describe various different expansion and compression processes depending on the value of the polytropic index. Examples are
