For the study on porous cement clinker

researchers solve the equations of Darcy's law and local no-thermal equilibrium heat transfer based on the theory of heat transfer of fluid flow in porous media. However

the solving process is complex and not convenient for engineering application. A kind of straight pipe equivalent heat transfer model was established by introducing the theory of straight pipe heat exchange to unit body of porous cement clinker. In order to decrease the difficulty of the solving process

the methods and ideas based on the theory of straight pipe heat transfer were used to solve the heat transfer process of porous cement clinker. On the premise of ensuring calculation precision

the changes of temperatures of both clinker and gas with time were obtained. A self-designed experimental equipment was used to verify the temperature expressions at different porosities. The calculation results basically agreed with the experimental data

which verified the feasibility of straight pipe equivalent heat transfer model.
