ABSTRACT
This paper describes the results of a recent study of thermal effects on the fluid dispersion relation of dust acoustic waves. In this study, different comparisons are made of the dispersion relation, e.g., wave frequency versus wave number and wave number versus dust number density, which show that dust kinetic temperature is in the range 200–400 eV. An independent measurement of the dust kinetic temperature using stereoscopic particle image velocimetry techniques confirms this range of dust kinetic temperatures.
