ABSTRACT

An approach based on the calculation of rotational dynamics coupled with the
speed calculation is applied to the design of turbomachines or wind turbines. In the case
of turbomachines, 3D flow is analyzed in two stages by the quasi-dimensional S2
(meridian flow) - S1 (flow dawn to dawn). In the first stage, bound and free vortices
simulating the blades are spread in a consistent way along the azimuthal direction, the
flow becomes axisymmetric and can be analyzed in the meridian S2. In the second step,
we analyze the flow blade to blade assumed confined in each layer of revolution defined
by the first step. This reverse calculation is used to the design of a wind turbine in a solar
chimney.

• ##### Article: Experimental and theoretical performance of a demonstration solar chimney model—Part I: mathematical model development
[Hide abstract]
ABSTRACT: The solar chimney is a natural draft device which uses solar radiation to provide upward momentum to the in-flowing air, thereby converting the thermal energy into kinetic energy. A study was undertaken to evaluate the performance characteristics of solar chimneys both theoretically and experimentally. In this paper, a mathematical model which was developed to study the effect of various parameters on the air temperature, air velocity, and power output of the solar chimney, is presented. Tests were conducted on a demonstration model which was designed and built for that purpose. The mathematical model presented here, was verified against experimental test results and the overall results were encouraging. © 1998 John Wiley & Sons, Ltd.

• ##### Article: Solar Chimney Turbine Performance
[Hide abstract]
ABSTRACT: Thesis (PhD (Mechanical and Mechatronic Engineering))--University of Stellenbosch, 2002. This project investigates the performance of solar chimney power plant turbines. A solar chimney power plant consists of a tall chimney surrounded by a transparent deck or solar collector. The sun heats the air in the collector through the greenhouse effect. A turbine extracts energy from the hot air rising up the chimney. An investigation of the requirements and operation of such turbines is needed. Correct matching of the turbine to the plant requires the determination of the turbine operational range and other requirements. An air-standard cycle analysis is extended to include component and system losses. Simple steady-state and transient collector models are added to take into account the coupling effect of the collector air temperature rise and mass flow rate on the turbine operation. The predicted turbine operational range for a representative day shows that the expected pressure drop in a full-scale solar chimney turbine is significantly higher than has previously been predicted. A turbine design method is developed and used to design a turbine for the representative day. The methods can easily be extended to include more operating points for a full year of operation. A turbine layout is suggested that uses the chimney support pillars as inlet guide vanes (IGVs). These introduce pre-whirl to the turbine and reduce the amount of exit whirl thus decreasing the kinetic energy at the turbine exit. Non-radial inlet guide vanes add to the torsional stiffness of the chimney base. A matrix throughflow method is used to design the radial to axial duct between the IGVs and rotor. The turbine blade profiles are simulated using a surface-vortex method. This is coupled to an optimisation scheme that minimises both the chord length and maximum flow velocity of the profile to reduce blade drag. An experimental program investigates the performance of the turbine. Volume flow, pressure drop, torque and speed are measured on a scale model turbine to map the turbine performance over a wide range. The velocity and pressure profiles are measured at two design points to investigate the flow through the turbine in more detail. These are compared to the design predictions and used to improve the design method. The experiments show that the design of a solar chimney turbine with a total-to-total efficiency of 85 % - 90 % and total-to-static efficiency of 75 % - 80 % is possible. Analysis of the experimental results shows that the turbine efficiency can be improved.
