The purposes of this laboratory are to 1) measure the pressure distribution around a circular cylinder at different velocities (and reynolds number) 2) calcu. A spectral method which employs trigonometric functions and chebyshev polynomials is used to compute the steady, incompressible laminar flow past a circular cylinder. The present study numerically investigates two-dimensional laminar flow past a circular cylinder rotating with a constant angular velocity, for the purpose of controlling vortex shedding and understanding the underlying flow mechanism.
Velocity and pressure distribution for flow over a cylinder for starters, let's just look at the velocity and pressure fields relating to flow past a circular cylinder to gain a qualitative understanding.

Part 1 of this two-part paper solves the two-dimensional problem of the unsteady flow of a viscous incompressible fluid past a circular cylinder subject to impermeability and navier-slip conditions. The turbulent flow past a circular cylinder (re=3900) was computed by large eddy simulation (les) the objective was not to investigate the physical phenomena of this flow in detail but to study numerical. Keywords: flow past a circular cylinder lab report the aims of the investigation is to measure the pressure distribution on the surface of a smooth cylinder placed with its axis perpendicular to the flow and to compare it with the distribution predicted for frictionless flow, and to calculate the drag coefficient of the cylinder.

Abstract—flow over circular cylinders with patterned the flow over circular cylinder had been subjected to intensive research for a long time a circular cylinder. The effects of different solidities on the flow in the near wake are investigated using smoke wire flow visualization, hot-wire anemometry, and measurements of the mean pressure at the cylinder surface, and the results are related to cylinder flow without a splitter plate.
