Experimental Investigations of Near-critical Fluid Phenomena by the Application of Laser Diagnostic Methods

Abstract Physics of supercritical fluids is extremely complex and not yet fully understood. The importance the presented investigations into physics twofold. First, approach links microscopic dynamics macroscopic thermodynamics fluids. Second, free falling droplets in a near to environment are investigated using spontaneous Raman scattering laser induced fluorescence/phosphorescence thermometry approach. resulting spectroscopic data employed validate theoretical predictions an improved evaporation model. Finally, thermal acoustics used investigate acoustic damping rates region pure
