Numerical and Mathematical modeling of dynamic thermal behavior of building

The comfortable habitat is necessitating the improvement of energy efficiency directly related to the heat. for this reason,this work is essentially focused on numerical and mathematical modeling of building dynamic thermal in the two-dimensional behavior. a zonal model is chosen for heat and mass transfer modeling. this approach,used to describe the temperature and air velocity parameters in the building with a very fine degree of accuracy however,the equations of continuity,momentum and energy are already known to be the main physical problem based on primitive variables without giving analytical solutions. indeed,numerical methods proved their importance while the adi alternating direction implicit method is used in this work,and our findings showed as expecting various variations of the air speed dependently to heat spread in different instants with an interesting dynamic thermal behavior. these results are confirmed by other studies encouraging the implementation of new subjects in this field. © 2017,university of mohammed premier oujda morocco.
