Axial-Flow Compressors: A Strategy for Aerodynamic Design by Ronald H. Aungier

By Ronald H. Aungier

This booklet offers a radical description of an aerodynamic layout and research platforms for Axial-Flow Compressors. It describes the elemental fluid dynamic and thermodynamic ideas, empirical versions and numerical tools used for the total diversity of tactics and analytical instruments that an engineer wishes for almost any kind of Axial-Flow Compressor, aerodynamic layout or research job. It experiences and evaluates numerous layout options which were instructed within the literature or that have been discovered to be powerful. It provides a whole description of a precise operating approach, such that readers can enforce all or a part of the method. Engineers accountable for constructing, conserving of bettering layout and research platforms can profit significantly from this sort of reference. The know-how has develop into so advanced and the function of desktops so pervasive that in regards to the simply manner this is often performed this day is to pay attention to a particular layout and research method. the writer presents useful technique in addition to the main points had to enforce the recommended methods.

Org/about-a Thermodynamics • 33 simply by recomputing the fictitious constants between stages or between blade rows. The modest stage pressure ratios in axial-flow compressors almost always ensure that the model is sufficient. Indeed, this writer has used it extensively for industrial centrifugal compressor performance analysis, where stage pressure ratios are much higher and non-ideal working fluids are common. No case has been encountered to date where the pseudo-perfect gas model yields results significantly different from a full non-ideal gas model.

2-34). Note that Eq. (2-41) requires that cp be the specific heat per mole rather than per unit mass. For the original Redlich-Kwong equation, c = 0, and Eqs. (2-38) and (2-39) are not used. A mixture equation of state formed in this manner is applicable only to the vapor phase of the fluid. Although the above real-gas models apply to the more general two-phase flow problem, the composition of the two phases may be different and vary with state-point conditions, requiring special treatment. Axialflow compressors are not intentionally applied to two-phase flows, so the restriction to the vapor phase is not a concern in this application.

The through-flow analysis is widely used in both design and performance analysis. This involves solving the governing equations in the hub-to-shroud plane at stations located between blade rows. The flow is normally considered to be axisymmetric at these locations, but still three-dimensional because of the existence of a tangential velocity component. Empirical models are employed to account for the fluid turning and losses that occur when the flow passes through the blade rows. A simplification of this analysis is the “pitch-line” or “mean-line” onedimensional flow model, which ignores the hub-to-shroud variations.
