Among the existing designs of hydraulic pumps/PATs, "centrifugal" or "radial" units are the most used worldwide in a wide variety of application fields. [9] The name is derived from the radial path followed by the fluid in the rotor: from the centre to the periphery when running as a pump and in the opposite direction when flow is reversed. [10]
Axial-flow pumps; Centrifugal Pumps; Turbopumps; While creating a new design, AxSTREAM allows the user to start from initial inlet and outlet parameters, geometrical constraints, required mass flow rate (capacity) and rotational speed to perform preliminary design, 1D/2D calculation and optimization.
A centrifugal pump is an example of a radial flow turbomachine. Mixed flow turbomachines – When axial and radial flow are both present and neither is negligible, the device is termed a mixed flow turbomachine. [9] It combines flow and force components of both radial and axial types. A Francis turbine is an example of a mixed-flow turbine.
The Jonval turbine is a "mixed-flow" turbine design. Mixed-flow designs were well suited for the low-head applications common in the eastern United States. The smaller size, higher speed, higher power, lower cost, and ability to operate efficiently with variable water levels caused these and other types of hydraulic turbines to replace the ...
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and ...
A pump-jet, hydrojet, water jet, or jet drive uses a ducted propeller (axial-flow pump), centrifugal pump, or mixed flow pump to create a jet of water for propulsion. These incorporate an intake for source water and a nozzle to direct its flow out, generating momentum, and in most cases, employing thrust vectoring to steer the craft.
The continuous stirred-tank reactor (CSTR), also known as vat-or backmix reactor, mixed flow reactor (MFR), or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering. A CSTR often refers to a model used to estimate the key unit operation variables when using ...
Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...
