Abstract:

The paper is concerned with the properties a fluid has to have to admit mechanical similarity of flow fields. Two cases are distinguished, whether or not the fluids in model and prototype are the same. Proceeding from the requirements that have to be met by mechanically similar flow fields, necessary and sufficient conditions are given for the constitutive equations of the fluids. The general concept is applied to the flow of dissociating gases and to the flow of thermally radiating gases. Author
