De Haller number The de Haller number is defined as the velocity ratio of the trailing edge and the leading edge of a blade or a vane. This is a simple measurement of diffusion used in preliminary design work. The De Haller number should exceed 0.72. For final calculations, the diffusion factor is preferred [19]. Stage loading Stage loading is a measure of how much work is demanded by a turbomachinery stage and therefore the required “turning” of the flow. It is defined as the enthalpy change per unit mass flow of air divided by the blade speed squared. A lower stage loading leads to a higher efficiency, but in turn, more stages are required [11]. Flow coefficient The flow coefficient relates primarily to component size, and if it is non-optimal to the efficiency. It is defined as the axial velocity divided by the blade speed. A typical value is 0,4 – 0,8 [20]. Deflection The deflection is the difference between the angle of the relative velocity of the leading edge and the trailing edge. It is a direct measure of flow turning. A high deflection would imply a high rate of diffusion in a compressor or acceleration in a turbine. 3.3.2.2 Flow path The flow paths for the turbomachinery components have been evaluated using three different design approaches: constant mean diameter, constant outer diameter and constant inner diameter. The flow path selection will influence some of the above mentioned parameters, and they all have some advantages and disadvantages [19]. In modern designs an intermediate choice of constant inner and constant outer is often made. Figure 5 shows the three designs of a compressor.
