12 clearly show different slopes of the pressure traces during expansion, indicating differences in the expansion polytropic
This author believes that this actually helps explain why kinetic theory falters in polytropic
stars, wherein high-density gases collide in a condensed matter fashion hence one must use polytropic
An analytical model, is formulated considering polytropic
change in the gas state and fluid compressibility, and validated using the measured data.
Combustion attributes such as the mass fraction burnt profile, including combustion phasing in terms of 50 % mass fraction burnt (CA50), were calculated using the fast net heat-release method with a constant polytropic
The clearance volume ratio and compression polytropic
exponent were found by curve fitting.

gases," Archive for Rational Mechanics and Analysis, vol.
The thermodynamic systems are commonly described with polytropic
relation and an assumption of a constant value of the polytropic
The human body in the process of life is exposed to complex environmental factors, polytropic
actions that contribute to the formation of altered reactivity of the organism, increasing the risk of diseases [2-4].
The only formula shown explicitly in this article indicates the polytropic
efficiency calculated for an ideal gas.
As the compression and expansion processes in the engine are not adiabatic and accompanies heat transfer, a polytropic
Under the vibrations, the behavior of the compressed air within the air spring system is polytropic
Another variant of the efficiency-based model incorporate theoretical polytropic
compression model that requires a fixed polytropic
