Fluid Dynamics and Circular Plate

To achieve a good volumetric technique, the experimenter needs to be able to correctly complete certain procedures.

Another type of coherent structure are ‘rolls’, which are ‘pairs of counter-rotating streamwise vortices that are the dominant vertical structures in the near-wall region defined by y+ < 100’[2]. They account for streak production also, as the fluid being pushed outwards between the rolls has reduced axial velocity, creating a velocity profile which is inviscidly unstable, and also associate with bursting and lift-up.

Firstly using the Bernoulli’s equation, we can explain the relationship between the pressure of a fluid and its velocity for two points that lie on the same single streamline. [1]

To receive accurate angular displacement measurements, the outputted angular velocity readings had to be filtered to remove noise present within the sensor, before being scaled by equation 2. Noise was recorded within the range of -2degrees/s to 2degrees/s, and therefore a high pass

The average depth value shall be similar to the required depth value of the air gap needed for the experiment.

The initial axial and bending stress distributions as well their resultants stress distribution can be theoretically drawn across the width of the C-clamp to visualize a shift of the neutral axis, included in Appendix C.

NOTE: Before commencing the experiment, the cantilever strip was bent at about 20mm off its edge to prevent the weight hanger from slipping off. The hanger was then loaded and deflections measured till collapse of the cantilever arm.

The objective of the experiment is to understand the meaning of displacement, average velocity, instantaneous velocity, average acceleration and instantaneous in one-dimensional motion. The first experiment was to calculate the average and instantaneous velocity. We first

Where λ=u_w/u_∞ is the plate velocity ratio that represents the direction and magnitude of the moving plate.

The plate under study is a rectangular plate simply supported at four ends with load force at it extremes, the study aims to find the nodal displacement of the plate caused by the load. Also the plate was modeled in FEA software for comparison reason and to check the algorithm accuracy, the plate specification is as follows:

The tube or tunnel reactors employed can be coupled inductively with a coil or capacitively with electrode plates. In both cases,

Now we applied some voltage V such that the upper plate moves with y displacement.
