## What is/are Non Ideal Gas?

Non Ideal Gas - This manuscript aims to deal with the one-dimensional unsteady flow of non-ideal gas with monochromatic radiation under the influence of a magnetic field, where the invariance method of the Lie group of transformations is applied in a cylindrically symmetric motion.^{[1]}The dust consists of tiny solid particles continually scattered in a non-ideal gas.

^{[2]}A non-ideal gas approach and fugacity coefficient were also considered in the calculation.

^{[3]}A rigorous analysis of the association behaviour of methanol vapour confirms that dimers and cyclic tetramers play an important role, but physical non-ideal gas behaviour must also be taken into account.

^{[4]}It is proved that TdU entransy and TdH enthalpy-entransy are not state functions for thermodynamic systems with non-ideal gas substances, so the entransy transfer analysis methodology is constructed based on entransy process functions for generic systems operating with thermodynamic cycles.

^{[5]}The dusty gas is taken to be perfectly conducting mixture of non-ideal gas and small inert solid particles of micro size, in which solid particles are continuously distributed.

^{[6]}This enabled in combination with the results for air an assessment of the impact of non-ideal gas dynamics on the form drag of a cylinder in the considered highly subsonic flow regime.

^{[7]}Both approximations have been implemented with complex multi-parameter equations-of-state based on the Helmholtz free energy, taking into account the non-ideal gas flow behavior of steam and carbon dioxide.

^{[8]}It was compared with the ideal gas model to clarify the differences and non-ideal gas characteristics of He–Xe.

^{[9]}Similar to the spacecraft extensions of TAU, HyperCODA extends CODA for applications at high Mach numbers, including non-ideal gas thermodynamics, gas mixtures, and chemistry.

^{[10]}The compressor, in particular, operates in a thermodynamic condition close to the critical point, whereby the fluid exhibits significant non-ideal gas effects and is prone to phase change in the intake region of the machine.

^{[11]}The selected configuration was considered as representative of the high-pressure stages of high-temperature Organic Rankine Cycle (ORC) axial turbines, which may exhibit significant non-ideal gas effects.

^{[12]}Non-ideal gas flow behaviors are investigated by an Enskog-Vlasov type kinetic model considering the simultaneous effects of gas molecule size (volume exclusion) and long-range intermolecular attractions at the molecular level, which corresponds to the real gas equation of state at the macroscopic level.
