Predicting root mean square (r.m.s) pressures from computed velocities and mean pressures.

There is a need to calculate root mean square (r.m.s.) pressures from the output of steady-state computer programs. We know much less about calculating r.m.s. pressures than about calculating r.m.s. velocities. R.m.s. pressures can be quickly estimated from calculated mean pressures, mean velocities and r.m.s. velocities using the equations in this paper. The equations have been used in \Mind Engineering but can be applied in any turbulent flow where pressures are required.

Averaged pressure coefficients for rectangular buildings.

Presents and discusses mean pressure coefficients averaged over the entire side of a building, obtained from measurements made on models of rectangular flat-roofed buildings made in a boundary layer wind tunnel. Describes measurement technique and data collection. Pressure coefficients based on either a local reference wind speed or a reference wind speed measured at the level of the building have been computed. Gives example and a comparison with existing building codes and standards.
