Liquid jets are widely used in cleaning operations in the ground deicing aircraft sector. The present work investigates heat transfer and momentum forces created by hot turbulent propylene glycol jet impinging on a horizontal plate at temperature below zero point A cylindrical liquid jet impinging on an horizontal plate flows radially outwards from the point of impingement to form a wall film. A model for the simulation of aircraft ground de-icing is proposed. It is conjectured that flow due to impinging hot oblique jet on a horizontal plate depend mostly on the nozzle diameter, the jet velocity, the nozzle pressure, the jet inclination angle and the distance to plate (standoff). The Volume Of Fluid (VOF) model coupled with the film formulation is employed using Computational Fluid Dynamics (CFD) to capture the interface in multiphase flow (propylene glycol-ice-air). The three-dimensional Navier-Stokes and energy equations are numerically solved using a finite-volume discretization under steady and unsteady conditions with the RANS turbulence models. A conjugate heat transfer formulation is used to couple the heat transfer at the interface between the solid and fluid. Comparisons are made between CFD results and experimental observations reported in the literature for heat transfer prediction, and a good agreement between these two can be observed. This work is novel in that it first proposes a model to study parameters that govern deicing with propylene glycol jet.
