What is a polytropic exponent? – WisdomAnswer

WebThe polytropic index of solar wind near 1 AU is close to the value of the adiabatic process (γ = 5/3) (e.g., see: [3,4,5,6,7,8,9,10,11,12]). Note that values of polytropic index smaller than the adiabatic value of 5/3 are used to account for unspecified heating mechanisms, such as turbulent heating. WebThe 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.
