TALK=T;RUN(1,1) DISPLAY This case illustrates the use of In-Form for creating flow resistances and guide vanes in the lower part of the box. A air enters a box through an aperture in one side near the bottom, and leaves through a similar aperture near the top. Flow resistances and guide vanes in the lower part of the box, which are intended to cause the upward flow in the box to be nearly uniform, are introduced via In-Form source formulae. Their disposition was chosen directly in a zone where the flow changes direction. There are two resistances with different factors. First is located directly before the input. It is intended for prevention the distribution of a inlet flow inside of the box in a horizontal direction. Second in the small area above the input. It is intended for zeroizing of a horizontal velocity component. The guide vanes are located also in the area before the input and is intended for smooth turn of a inlet flow. Interesting changes include: changes to the inlet velocity and use resistances and vanes in different combinations. The Q1 contains PHOTON USE commands.
