|초록||At Grashof numbers 1010, 5X1010 and 1011 nonlinear partial differential equations for two dimensional thermal circulation of air in a rectangular enclosure heated, from below are solved numerically by finite difference explicit methood in time-dependent form. Two vertical walls and ceiling are held at low temperature and floor at high temperture.
Results are compared with From's numerical solutions at 109≤NGr <1013.
The effective draft temperature fields are also obtained to examine cold draft problem, 'there included a line of constant effective draft temperature -1.667。C which is essentially Houghten's 80% comfort data.
