Using simple boundary condition, the temperature gradient along the z direction is a constant while the generative internal heat is not considered.

Firstly,the natural fermentation without temperature control is performed;the variation of heat releasing is researched,and the inner heat source of wine fermentation is identified.

This heat release was defined as the inner heat source of wine fermentation.

The thermal field of test piece has been calculated according to the model,and the intensity of inner heat source,thermal conductance and position of cable have been studied by the model.

Study on internally heated hot runner system;

The results showed that PPD polyurethane elastomers could be applied in tire surface material with lower interior heat build-up and higher elastic resilience property than MDI polyurethane.

Investigation of hourly emission status of internal heat sources in Beijing residences;

Maximum temperature history in the packed bed of combustible material with internal heat source was studied numerically under the boundary conditions of convection and constant wall temperature.

To check the thermal equilibrium assumption between solid matrix and fluid in porousmedia with internal heat source, the forced convection in channels filled with packed bedswith heat generation was analyzed numerically with the extended Darcy model for flow andthe two energy equations in which the thermal equilibrium assumption is released.
