2.4. Methodology for evaluation of U and hfp
Heat transfer coefficients U and hfp (Fig. 2) were calculated by
using a methodology developed earlier by Singh et al. (2015c).
For this purpose, the heating rate index of the liquid and particle
were used to compute the U and hfp in reciprocating agitation. In
the revised methodology, values of hfp were estimated by fitting
the predicted temperature profile of the cold-spot (particle center)
