This paper reviews the development of computational fluid dynamics (CFD) specifically for turbomachinery simulations and with a particular focus on application to problems with complex geometry. The review is structured by considering this development as a series of paradigm shifts, followed by asymptotes. The original S1-S2 blade-blade-throughflow model is briefly described, followed by the de...

Cycles using supercritical carbon dioxide have been recognized as potential future power technology. However, the turbines in these systems tend to experience very high rotational speeds and entail small physical sizes, which can affect on overall feasibility. One turbine type having overcome some of described challenges is radial outflow turbine. its use has not yet extensively studied since t...

Airflows between centrally clamped, rotating, rigid disks are investigated with respect to the type of flow pattern, the parameters that influence nonuniform flow, and the effects of various flow patterns on disk stability. The experimental method uses a waterflow modeling technique for the airflow. The observed flow patterns are highly unsteady. The configuration and position of the shroud and...

Three-dimensional throughflow models represent a turbomachinery cascade via force distribution without the need for detailed geometric modelling in numerical solution, saving consistent computational resources. In this paper, we present application of body method on an axial transonic fan implemented into in-house tool axisymmetric simulations. By systematic comparison local and integral quanti...

Imposing axial flow in the annulus and/or radial flow through the cylindrical walls in a Taylor– Couette system alters the stability of the flow. Theoretical methods and numerical simulations were used to determine the impact of imposed axial and radial flows, homogeneous in the axial direction, on the first transition of Taylor–Couette flow in the framework of convective and absolute instabili...

The nature of solids-liquid flows often results in non-uniform profiles of solids volume fraction and axial solids velocity across the flow cross-section. In order to measure the solids volumetric flow rate in these situations it is necessary to measure the profiles of the local solids volume fraction and axial solids velocity and to obtain mean values of the solids volume fraction, solids axia...
