dc.description.abstractENGLISH ABSTRACT: The aim of this thesis is to investigate the influence of a forced cross-flow component at inlet as an isolated system effect on the performance of rotor-only axial fans. The off-design condition is imposed by inserting inlet pipe sections - mounted at angles to produce ratios of 0, 0.25, 0.5 and 1 between the cross-flow and perpendicular on-flow velocity components - between the plenum chamber of a standardised test facility and fans of 1542 mm diameter. Three fans are investigated over a wide envelope of flow rates and blade angles.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Die oogmerk van die tesis is om die invloed van skuins invloei as 'n geïsoleerde stelseleffek op die werking van aksiaalwaaiers te ondersoek. Pypseksies is gemonteer tussen die plenumkamer van 'n standaard toetsopstelling en die inlaat van drie waaiers met 1542 mm deursnit. Die inlaatpype is teen 'n hoek gemonteer om dikrete waardes van dwarsvloei (verhoudings tussen dwars- en inlvloei-komponente van 0, 0.25, 0.5 en 1 respektiewelik) te bewerkstellig, terwyl die waaiers se reaksie oor 'n wye veld van volumevloei en lemhoek getoets is vir elke opstelling.af_ZA
