Numerical modelling of plasma spray process

Numerical modelling of thermal spray systems

The purpose of this paper is to present a brief overview of the MD* thermal spray process, review the current existing models of heat transfer and fluid mechanics relevant to this process, outline a simplified thermal model implemented together with the results, and discuss the activities required for the implementation and verification of an accurate temperature model of the MD* thermal spray ...

Experimental and numerical modelling of nasal spray atomisation

Spray atomization is a common process found in different industries, where sprays under high injection pressure are widely recorded in the literature. Nonetheless, research on spray breakup mechanism under low pressure in pharmaceutical industry is still relatively rare. Numerical model in the Lagrangian approach was modified for simulating the spray formation from a nasal spray device in the c...

Numerical Vlasov-Maxwell Modelling of Space Plasma

The Vlasov equation describes the evolution of the distribution function of particles in phase space (x, v), where the particles interact with long-range forces, but where short-range " collisional " forces are neglected. A space plasma consists of low-mass electrically charged particles, and therefore the most important long-range forces acting in the plasma are the Lorentz forces created by e...

Modelling of Gasoline Spray Impingement

This paper is concerned with aspects of gasoline spray droplet impingement simulation, for which an improved model has been developed for predicting the outcomes of spray droplets impacting on a wall. The model is assessed by simulating experiments on oblique spray impingement in a wind tunnel. This is done with the aid of a specially-devised procedure for deducing the specification of initial ...
