“…This equation is based on 278 individual data points embracing wide ranges of conditions (0.5 Յ n Յ 2; 1 Յ Pr Յ 400; 5 Յ Re Յ 200) and it correlates the present numerical data with the maximum and average deviations of 10.2 and 2.6%, respectively. For the Newtonian case (that is, at n ϭ 1) it reduces to the correlation proposed by Feng and Michaelides 40 and also at Re ϭ 0 for Newtonian fluids it reduces to the expression of Acrivos. 41 Similarly, Eq.…”

“…The problem is also well suited to testing the numerical code since it has a simple axisymmetric geometry that can be easily defined in cylindrical co-ordinates. There is an extensive literature on heat transfer from droplets, allowing us to compare our results to previously published material [1,38].…”

“…To make the problem more tractable interface movement is often ignored [1] or prescribed a priori [2]. Such assumptions may be justified: when small water droplets are sprayed into air [3] it is quite reasonable to neglect surface deformation since surface tension keeps the droplets spherical.…”

“…The present analysis starts from the following observation of Pfeffer [50]: predictions based upon creeping flow assumption remain accurate for Reynolds number as high as 50. First, we made numerical simulations with Z p = constant = 1, keeping Pe constant and varying Re (this kind of investigation was suggested by [70,71]). The results obtained for Pe = 100 and Pe = 1000 are presented in Tables 5 and 6.…”
