The recent years have seen much development in the field of Computational Fluid Dynamics. This is the application of computers to solve fluid problems. One of the advantages of CFD is the speed and the efficiency thereof. Again, after the final analysis, the application of CFD over the traditional methods is cheaper in the long run. Reynolds Osborne showed that depending on the value of Reynolds number, the flow can either be laminar or turbulent. There however exists an intermittent flow type, called transitional, where both flow characteristics exists. The behaviour of the flow within this region is therefore very unpredictable. In this research, the flow within this region was investigated. The influence of geometry on the properties was investigated.  This was by introducing a constriction and an obstacle in a smooth flow to produce turbulent effect and, unavoidably, transitional behaviour. The slow development and change in the flow streamlines to create vortices was observed. The geometry of the pipe had a major influence on the behaviour and the rate of dissipation of energy. The introduction of an obstacle reduced the maximum kinetic energy and also the point where it was observed. A pipe of diameter 0.12 m was used for this research. The velocity required to produce a near-critical-value Reynolds number calculated to 0.0385m/s.
