فراروند ِ بُلگشتی
Fr.: processus polytropique
A thermodynamic process that obeys the relation:
PVn = C, where P is pressure, V is volume,
n is any real number, called the → polytropic index, and
C is a constant.
If n = 0, then P = C and it is an
→ isobaric process.
If n = 1, then for an → ideal gas PV = NkT =
C and it is an
→ isothermal process.
If n = γ, → adiabatic index, then for an ideal gas it is an
→ adiabatic process.
→ polytropic; → process.
