Numerical and experimental investigation of swirling flow in a conical diffuser

An experimental investigation of performance of a 3-D solar conical collector at different flow rates

The shape of a solar collector is an important factor in solar-to-thermal energy conversion. Conical shape is one of the stationary and symmetric shapes that can be employed as a solar water heater. Flow rate of working fluid on the solar collector has an important effect on the efficiency of the collector. The present study is an experimentally investigated of the performance of the solar coni...

Numerical Investigation of the Campbell Diffuser Concept

Campbell diffusers have a unique feature in that they lack axial symmetry in the end walls. It has been proposed that the asymmetry of the end wall in a vaned diffuser can be tailored to improve its performance. This concept is applied to the redesign of two vaned diffuser configurations: (1) diffuser with straight leading edge; (2) diffuser with parabolic leading edge. In the redesign, the ori...

Numerical Simulation of a Confined Swirling Flow in a Model Gas Turbine Combustor

Experimental and numerical investigation of the competition between axisymmetric time-periodic modes in an enclosed swirling flow

Time-periodic vortex flows in an enclosed circular cylinder driven by the rotation of one endwall are investigated experimentally and numerically. This work is motivated partly by the linear stability analysis of Gelfgat et al. J. Fluid Mech. 438, 363 2001 , which showed the existence of an axisymmetric double Hopf bifurcation, and the purpose of the experiment is to see if the nonlinear dynami...
