For the current investigation, the gas liquid two-phase media are modeled as air involving fine droplet or droplets of water. A cylinder-piston system is modeled which contains air with single or multiple droplets of water. The compression process is achieved by the movement of the piston. During the compression process, thermodynamic properties such as temperature and pressure are investigated in detail. Analytical equations have been derived to obtain the transformation in fluid properties. The results thus obtained are discussed for different conditions of overspray and initial absolute humidity of the air inside the cylinder. The thermodynamic curves obtained are seen to deviate significantly from the dry isentropic curve ( PVγ=constant) with decreasing droplet diameters and increasing mass of droplets. This deviation can be associated with the latent heat absorbed by the evaporating droplets during the process of compression.
