TALK=T;RUN(1,1) DISPLAY FULLY-DEVELOPED FLOW IN A DUCT OF RECTANGULAR CROSS-SECTION This case is similar to case 249 (the square cavity with a moving lid); but it is here supposed that there is flow normal to the square cross-section, and that the duct is long enough for the velocity distribution to have become fully developed. Opportunities are provided to change:- * the non-dimensional longitudinal pressure drop, * the Reynolds number based on lid velocity and lid width, * and the aspect ratio of the duct cross-section. PHOTON USE commands are supplied for ease of display. enddis PHOTON USE p view z msg Grid gr z m msg - msg Pressto continue pause gr off;gr ou z 1;red msg Contours of longitudinal velocity con w1 z m fi;0.001 msg - msg Press to continue pause con off;red msg Contours of temperature con h1 z m fi;0.001 msg - msg Press e to END enduse ************************************************************ Group 1.
