Stagnation Pressure Changes in Unsteady Flow
Published online by Cambridge University Press: 07 June 2016
Summary
The changes in stagnation pressure produced by movement of rows, arrays and sheets of vortices are derived. By applying Preston’s result for a single row of moving vortices to continuous vortex sheets, the time mean stagnation pressure downstream of a row of blades with fluctuating circulation is derived. It is shown that if the blade circulation varies due to the potential flow fields of the neighbouring blades then the time mean stagnation pressure may change with location.
