| 摘 要： | The beat flux distributions were measured by using transient method for an argon dc laminar plasma-jet flow impinging normally on a plate surface embedded with copper probes.Different powders were coated on the probe surfaces and the effect of powder coating on the heat transfer from jet flow to the probe surface was examined Experimental results show that the maximum values of the heat flux to the probe increase with the coating of fine metal powders,while for the surfaces coated with fine ceramic powders,the maximum values of heat flux decrease,compared with that to the bare copper probe surface.
