If the specific heat c of the polytropic change is zero, the polytropic process becomes an adiabatic one (dQ = 0). … Isothermal Process- it is the process in which the temperature of the working substance remains constant during expansion or compression.
Hyperbolic Process- it is the process where the gas is heated or expanded in such a way that the product of its pressure and volume remains constant. … In contrast, an adiabatic process is where a system exchanges no heat with its surroundings (Q = 0). In thermodynamics, an isothermal process is a type of thermodynamic process in which the temperature of the system remains constant: ΔT = 0. the case n ➝ ∞ corresponds to an isochoric (constant-volume) process. … the case n =, pV = constant, corresponds to an isentropic (constant-entropy) process. There are some special cases of n, which corresponds to particular processes: the case n = 0, p= constant, corresponds to an isobaric (constant-pressure) process. The polytropic process equation can be used to compute a crank angle based curve of C (where n can be estimated). Where P is the pressure, V is specific volume, n is the polytropic index, and C is a constant. Any undergraduate engineering thermodynamics text should have a plot showing the true P-V diagram. As an example, consider a real engine cycle. No, all thermodynamic processes are not polytropic. Where P represents the pressure, V represents the volume, n represents the polytropic index, and C is a constant.
