... with extensive pitot-static axial wake surveys and use of Particle Image Velocimetry, PIV, to study the behaviour of the tip vortex. PIV results are given for one axial station at 55% x/c downstream of the trailing edge. The steady results are analysed to show the size and strength of the tip vortex...

... The proposed ITTC recommended procedures in measuring the elastic modulus, flexural strength, and specific weight of model ice are described. The basic theory is given, potential sources of error are identified, and comments are invited. equation strength ice committee thickness...

The body surface is discretized with many surface elements and the unknown strengths of the source and sink at each surface element are assumed to be constant. The velocities at surface elements are computed and saved...
