) Abstract: This paper proposes an approach to fabricate the hydroxyapatite coatings by powder spraying at normal temperature
In this paper, through establishing two-dimensional symmetric model, numerical analysis of gas-particle two phase flow is carried out by finite volume method
The effect of different spraying distance, nozzle exit radius, nozzle thoat radius and pressure on the gas axis-velocity and particle velocity is investigated
The simulation results will benefit optimal design of nozzle and spraying process
