Heat and Mass Transfer in 2-Propanol Droplet Evaporation: Analysis Modified Stagnant Film Model

Research output: Contribution to journalConference articlepeer-review

Abstract

Heat and mass transfer is an evaporation process from liquid droplet that occur in spray drying technology. So, it becomes important to understand the basic elements of spray drying, namely droplet. The formation technology involves drying is used in many industries. Various models of analogies of heat and mass transfer analogies have been formulated, with the aim of obtaining the characteristics that occur in the system. The analogy model most often used to obtain heat and mass transfer coefficients from droplet is the analogy model Ranz W. E. and Marshall W. R. The analogy has requirements, including the Lewis number (Le) which ranges in the number one. The purpose of this experiment is to compare the results obtained from the analogy of the Ranz-Marshall equation model applied to the droplet by making a modification of the C1 and C2 values that exist in the stagnant film model. In this experiment, the analysis results obtained from the modification of the stagnant film model is that the heat transfer phenomenon that occurs in droplet does not yet fully have good results. Where the value of C1 still cannot represent the value that can be used to obtain C2 properly.
