  Objectives
  1. Study the influence of a cross-flow on spray impact relatively to the mechanisms of secondary atomization along the period of injection, and also on the amount of liquid deposited on the surface.

  2. Study the variability of impact regimes and analyze the outcome of considering multiple drop impacts and the dynamic behaviour of the liquid film.

  3. Study the heat transfer regimes associated with spray impact, analyze heat transfer processes dependence on operating conditions, develop new concepts adequate to describe spray impingement heat transfer and develop accurate spray/wall heat transfer correlations for application in CFD models.
