... ABSTRACT This paper investigates the flow through and around a square array of cylinders. The investigations were performed numerically by RANS simulation with kω-SST turbulent model using OpenFoam. The effects of volume fraction on the drag coefficient have not been studied completely yet...

... on the obtained data, Reyonolds diagrams were constructed; the drag coefficient of icebergs was determined by two different methods; it is shown that the main size influencing on the resistance force of an iceberg is it's length (the largest linear size). As a result of the performed regression analysis, formulas...
