Threr are three phsical processing of heat transfer,mass trasfer and convection in coaxial powder flow. Temperature field of coaxial powder
is important for laser manufacturing.Computer simulation of temperature field has been made from two phases flow of powder/gas.Experimental measuremet of the temperature field has been finished by CCD camera. The total of themal distribution and its maxmau temperature in powder flow has been observed.
