   Abstract:
   Reports the results of a numerical study of the time-dependent removal of contaminant from a two-dimensional enclosure with one inlet and one outlet. The contaminant is generated beginning with the time t=0 by a concentrated source located inside the enclosure. The contaminant is removed by the through flow established between the inlet and outlet ports. The flows studied cover the laminar and turbulent regimes represented by 30⩽Re⩽3000, where Re is the Reynolds number based on the inlet width and mean velocity. The effectiveness of the contaminant removal scheme is documented in terms of the removal efficiency η_r, the volume-averaged concentration of contaminant C¯, and the critical (clean up) time t_c. The effects of Re, ventilation jet orientation and source location are reported. It is shown that the movement and distribution of contaminant is complex and depends strongly on the source location
