The influence of the parameters of the medium on heat transfer is investigated for all combinations of dimensionless criteria. Heat transfer and hydrodynamics under forced convection in porous microchannels with slip boundary conditions of the second order of accuracy are investigated. The research results showed the adequacy of the modeling of mixed and forced convection in porous microchannels by the LBM method. Using a network model for a capillary-porous material, a numerical method has been developed to calculate the transfer of heat and moisture through the porous structures of building materials. The calculation model is intended to determine the distribution over the thickness of the material and the character of the change in time of temperature, partial pressure of water vapor and moisture content of the material, depending on the conditions in the external air.   Product Description popup.authors Avramenko Andriy O Belyaeva Tatyana H.
