Technical and economic evaluation of the utilisation of wind energy at the SANAE IV base in Antarctica
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: The cost of powering Antarctic research stations by conventional diesel electric generator
systems is high (Steel, 1993). In order to reduce these costs and airborne pollution due to
the combustion of ...
An evaluation of a design method for mixed flow fans
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: Mixed flow fans find application in an operating region between that of axial flow and
centrifugal fans. The candidate investigated the working of these mixed flow fans and
formulated a design algorithm. ...
