In this paper, the gap effects on the aerodynamics and tonal noise generation of voluteless
centrifugal fans are studied based on different gap geometries. The study is motivated by the …

The input power to a centrifugal pump is optimized by changing the impeller blade exit
angle. In the optimization, blade exit angles of three meridional profile layers are selected as …

Volutes for radial-flow turbomachines (eg, centrifugal fans and pumps) are spiral funnel-
shaped casings that house rotors. Their function is to guide the flow from rotors to outlets …

The design of flow machines is still a difficult task, mainly due to the large number of free
geometrical parameters involved. Thus, design optimization techniques can be applied to …

Flow behavior inside rotors can be very complicated and with three-dimensional
characteristics. This fact added to a large number of free geometrical parameters that can be …

Comparative strength analysis of two popular options of the radial centrifugal fan impeller
design used in horizontal conveyor dryer for fine-grained raw materials is presented. Three …

The optimisation of high-speed fishing boats is different from the optimisation of other
displacement type vessels as, for high-speed fishing boats, the wave-making resistance …

Flow machines are very important to industry, being widely used on various processes.
Performance improvements are relevant factors and can be achieved by using optimization …

This article discusses the development, application, and validation of an optimization
method for the impellers of axial fans. The method is supposed to be quick, accurate, and …

Considering the deficiencies in uneven soil compaction and the too long vertical size that
exists in the soybean tillage sowing machine during conservation tillage, the profiling elastic …
