Abstract A hydrophilic gelatin suspension possesses thermal properties that may affect the ratio of convective to conductive heat transfer across a boundary. This ratio, also known as Nusselt's number, can represent laminar or turbulent flow regimes. In this study, thermal transitioning empirical values were determined using a gelatin as a polymer gel surrogate. The crux of this study was to (a) quantify heat transfer properties of the gelatin as a suspended semi-solid and (b) understand thermal profiles with respect to particle size and loading. We can adduce the existence of a thermally induced: lower rise velocity, stratified Nusselt number, and a boundary layer.
