WebNov 3, 2024 · Moreover, the results illustrate that the influence of the inlet HTF temperature on the melting performance is significantly greater than that of the inlet HTF flow rate. The liquid fraction of paraffin wax in the PCM unit with a higher inlet HTF temperature is always higher than that with a lower inlet HTF temperature at the same time. Webgreater IMFA=greater viscosity (sticker means that there are more bonds, so there is more energy required to split more viscous bonds) Vapor Pressure vs. IMFA vapor … WebThe results of an angiogram or arteriogram depend on the artery or organ system being examined.
