Abstract

Multiphase flows in which a large number of small droplets are dispersed in a gas, play an important role in a variety of applications. At sufficiently high mass and volume fraction the presence of the dispersed droplet phase directly modulates the flow through the exchange of momentum with the gas (Appl Sci Res 52, 309–329 (1994)) [1]. Dispersed multiphase flows may in addition show effects arising from phase transition. Turbulent spray cooling is an example in which the effect of phase transition is exploited to enhance the desired cooling rate (Int Heat Mass Transfer 41, 2601–2617(1997)) [2]. In this contribution we study turbulent flow in a differentially heated plane channel in which the dispersed droplet phase is treated as a discrete set of point particles whose motion in the carrier gas flow is tracked.
