潜热型功能热流体是一种新颖的储传热介质,其表观比热和传热能力比水大,在换热强化和能量输运领域有广泛应用.相变乳状液是潜热型功能热流体的一种.测定了相变微粒的粒径、乳状液粘度、表观比热和相变潜热,并探讨了不同关键因素(制备方法、乳化剂掺混比、温度和相变材料质量含量等)对热物性的影响.研制的相变乳状液粘度值明显小于文献值.
Latent heat function fluid is a novel storage heat transfer medium with apparent specific heat and heat transfer capacity greater than that of water, which is widely used in the field of heat transfer enhancement and energy transport. Phase change emulsion is latent heat function heat The particle size, emulsion viscosity, apparent specific heat and phase transition latent heat of the phase-change particles were measured, and the key factors (preparation method, emulsifier mixing ratio, temperature and phase change material mass content Etc.) on the thermal properties of the developed phase change emulsion viscosity values were significantly less than the literature value.
