A calculation method of the viscous flow around multi-component airfoils

The viscous flow around multi-component airfoils has been calculated by solving incompressible potential flow and boxindary layer problems iteratively. The potential flow problem is solved by a revised version of the 2D NLR panel method. A model transport equation of turbulent stress is employed to calculate the turbulent boundary layer. The...

Comparison of hot and cold subsonic jets in an external flow with reference to jet engine simulation

An experimental investigation was carried out concerning the effect of jet heating and external flow on the mean flow properties of a subsonic jet. A 60 mm diameter jet was tested in a wind tunnel at wind speeds of 0 and 60 m/s. Jet mach numbers varied between O.44 and 0.94 and jet total temperatures were 310 and 86O K. Velocity and temperature...

Measurements in a 2-D wake and in a 2-D wake merging into boundary layer: Data report

Extensive measurements of mean and fluctuating quantities in a 2-D wake shed from a flat plate and in the flow field of a 2-D wake merging into a boundary layer are described. The 'results are given in tabular and graphical form.

A model for the calculation of the properties of a jet in a three dimensional non-uniform main flow

A model is derived for the calculation of the properties of a jet exhausting into a non-uniform main flow, at an arbitrary angle to the initial jet direction. The model is a generalisation of an earlier jet-ina-main flow model for uniform main flows. Semi empirical input is limited to an entrainment relation and a relation for form factors of...
