Investigation on the concept and application of available stagnation pressure in the compressor
The aerodynamics design of compressor is definitely required for the flow direction
which
however
isn′t considered in the definition of stagnation pressure.So
the limitation of stagnation pressure appears when describing the performance of unsteady flow in high load fan/compressor.In order to deal with this limitation
available stagnation pressure was presented to consider the influnence on working capability of small flow volume caused by its velocity value and flow direction.And
according to the design demand of flowing in fan/compressor
the concepts of available stagnation pressure and pressure difference coefficent were defined at the level of engneering aplication.The application of available stagnation pressure can reflect more effectively the influence of flow direction on unsteady flow field in turbomachinery
making the performance characters of flow field change more sensitive to the change of quality of flow field.So the available stagnation pressure is useful to analyze the unsteady flow field.
