Abstract: 

 Heat transfer enhancement is still needed for the compactness and its smaller temperature difference of evaporator. This paper is introducing a mathematical model (Tailor-Chandra Model) for energy transport in plasma sprays process of a droplet. The model useful for calculate heat transfer through surfaces processed by thermal spraying. The model describes fluid flow of particle droplet during plasma spraying and its different energies: Thermal Energy (ETh), Surface Energy (ES), Kinetic Energy (EK) and the energy lost by way of radiation (ER) before deposition on substrate. A dynamic and thermal balance allows to calculate particle temperature and all energies of droplet during the spray process. As a result point of view, the model is able to show how molten droplets produced higher heat transfer as well as the effect of channel orientation in the low quality, low mass flux condition.
