Semi Empirical

The laminar flow around heaving axisymmetric and three-dimensional cylinders with damping plates is numerically studied for various Keulegan-Carpenter numbers. The Navier-Stokes equations are solved using OpenFOAM, which is applied to the flow on a moving mesh. For processing of results the semi-empirical Morison equation is used. Calculations are conducted for one cylinder, one cylinder with one disk, one cylinder with two disks, and one cylinder with one pentagonal plate. The calculated values are compared against experimental data.

Good Agreement

Predictions are made of heat transfer due to natural convection in long externally cooled vertical cylinders with uniform wall temperature containing a heat-generating fluid in laminar flow. Consideration is limited to fluids having Prandtl numbers of unity or above. Solutions are obtained for infinite and semi-infinite cells, with the lower end closed; the latter are in good agreement with experimental measurements in the completely closed cell under conditions appropriate to laminar flow.

Accelerating Flow

An analytical study is presented which describes the laminar accelerating flow of a thin film falling along a vertical wall. The approximate mathematical solution is given with emphasis on the growth and decrease of the boundary layer and film thickness, respectively. These resultant solutions are given in closed form and are found dependent upon two-dimensionless variables: φ2=3U0νgh02 and ζ2=1+2gh0x¯U02.
