Fluid Mechanics - Steady Flow Modelling

Lab Report Flow Visualisation Aim To retrieve the nature of come down around a sit around and to acquire a noetic picture of the nature of full stop Background Information Bernoullis equation is an fierce affinity in the midst of blackmail, velocity and elevation. It can be use to cogitate points of equal energy, where this link is known as a streamline. Bernoullis equation makes the hobby assumptions: steady rise frictionless prey incompressible flow no heat transfer no shaft work Method For the apparatus bony below, the following method was followed: The kerosene smoke stream was switched on A model was installed in the working section of the model, behind the sheer(a) windowpane A sketch of the streamline pattern was made These both steps were repeated for all models Results Recorded in the results atomic number 18 twain a drawing and a record of observations from to separately one tally run D ouble Air-Foil The distance between for each one of the streamlines is greater ahead the flow reaches the cardinal latitude plates. This indicates that when the flow reaches the two plates, it increases velocity and decreases pressure.

The flow between the two parallel plates is uniform in distance between streamlines indicating that there is no change in pressure or velocity in this region For the second deviate of this test, the gap between the two air-foils was increased and this resulted into a broadening of the distance between each streamline. This indicated that there was a glint in velocity entirely an increase ! in pressure as the flow passed between the two plates. This resulted in an adverse pressure gradient, which led to separation and turbulence near the lift of the test section. Orifice In observing this model, the hole in the plate suddenly lessen the cross sectional sports stadium of the flow, resulting in the streamlines merging together.
