Mass transfer coefficient for water evaporation by theoretical and empirical correlations

Evaluation and Generalization of 13 Mass-transfer Equations for Determining Free Water Evaporation

Thirteen equations based on the mass-transfer method for determining free water evaporation were expressed in seven generalized equations. These seven equations were then compared with pan evaporation at four climatological stations in north-western Ontario, Canada. The comparisons were based on monthly evaporation. Equations were compared by calibrating them on the entire data sets as well as ...

Heat Transfer Coefficient Correlations for Robert Juice Evaporators

CORRELATIONS FOR heat transfer performance in sugar factory juice evaporators are important for benchmarking and prediction of evaporator set performance. The correlation recently proposed by Broadfoot and Dunn (2007) (B&D) is examined and comparisons are made between it and formulae currently being used, in particular with the ‘Australian typical’ correlation, using data from Australian and ov...

Evaluation of Empirical Correlations for Predicting Gas Hydrate Formation Temperature

One of the important, practical and simple methods for hydrate formation conditionis empirical equations, and so far many empirical equations have been presented to predict thetemperature and pressure of hydrate formation. In this study, the methods and empiricalcorrelations have been reviewed and their predictive capabilities have been evaluated with ...

A Theoretical Mass Transfer Approach for Prediction of Droplets Growth Inside Supersonic Laval Nozzle

Proper estimation of droplet growth rate plays a crucial role on appropriate prediction of supersonic separators performance for separation of fine droplets from a gas stream. Up to now, all available researches employ empirical or semi-empirical correlations to define the relationship between droplet growth rate (dr/dt) and other operating variables such as temperatures (T and TL), Pressure (P...
