This paper describes a numerical study of laminar flow through building cracks such as those found around doors or windows. The mathematical model is based on the solution of the two‐dimensional conservation equations of mass and momentum by a finite volume method. The results are presented for two crack geometries, namely double‐bend and four‐bend cracks. The variation in local pressure coefficient along the crack walls and the velocity and pressure distributions within the cracks are described. The overall predicted pressure coefficient for the double‐bend crack for the double‐bend crack is compared with the results obtained using a correlation given by Baker et al. 5 .
