| Abstract: | A thermal emission velocimeter(TEV)technique to mea-sure particle velocity was discussed.The principle of the techniqueis the detection of thermal radiation from the hot particle in hightemprature two-phase flow.The technique used to measure particlevelocity in arc-heater jet and rocket shell spurt flames,to get moresatisfied results. |
