| Summary: | 11D were observable: for the 11D separation, the swirl along the pipe for different positions across the pipe and compared to the velocity profiles obtained by and for four azimuthal ogles around the pipe at each and the velocity profiles were generated by computer approximately twice as large as for the 11D be centered in the pipe and approach an axisymmetric between the two elbows (in plane and out of plane) to condition. The elects of increasing the separation disturbances decreased in value and the flow began to experiment for verification. For the experiments, a five-hole Pitot probe was used at dearest diameters flow progressed downstream, the flow field for one elbow and two elbows in plane while a single make an 90 degree bend: for 1 and 11 pipe diameters of pipe between the two elbows, two elbows arranged to position in order to obtain velocity profiles. As the separation. A double structure vortex was observable separation) and was still not centered at 19D. However single plane: for 1 and 11 pipe diameters of straight straight pipe between the two elbows. For each case, studied experimentally and numerically. The flow field the Fluent computational fluid dynamics (CFD) software The seeds of elbows upon the flow downstream were graphics. the simulation of the flow field was performed using the values of the velocity for a 1D separation are through two elbows arranged to make an S bend in a vortex was observable for two elbows out of plane. was calculated for five cases: through one elbow, was nearer the wall at 10D (compared to the 1D |
