In the casting and stamping process of automobile, ship, aerospace, other fields, improving atomization quality spray release agent can effectively solve problems difficult film removal, low efficiency, poor surface finish, greatly improve efficiency production manufacturing. The geometric model external mixing nozzle was constructed, calculation domain grid were divided. flow field velocity, liquid thickness, particle distribution, cooling amount calculated using fluid simulation software. Finally, an experimental platform set up for verification. With increase in distance between iron plate nozzle, velocity decreases from exit to periphery, frequency distribution D60–70 increases gradually. pressure ratio (K), gradually, thickness first, then gently decreases, decreases. influence gas on atomized is greater than that phase pressure, ion reaches peak value when K = 2. When 1.5, average increment absolute small, diameter changes least, D65 particles approximately same, effect most stable. spraying time 1 s, larger, smaller temperature drop will be. 2–4 change has little amount.
