On the right side of the window, there is a 3D-CAD preview and an area progression diagram of the meridional flow channel. In the meridional contour design window, modifications of hub and shroud contours can be made as well as shaping repositioning of the leading and trailing edges. It is an available option throughout every design step of CFturbo. The user can modify all geometrical values manually. On the right side of the window, we can see the essential physical values, an initial sketch of the meridional view, the impeller within the Cordier diagram, and an initial set of velocity triangles. Our software will provide a proposal for the main dimensions such as shaft diameter, suction diameter, impeller diameter, and outlet width. This gives a unique possibility to customize the code for own applications and to maintain proprietary information. Most of them are accessible and adjustable by the user.
The empirical correlations in CFturbo are taken from textbooks and research papers or are based on our data. An estimate for the efficiency is required as well. In this example, we use correlations for work coefficient, diameter ratio, and meridional deceleration. In the parameter section, we can select empirical function to design reasonable impeller main dimensions from the very beginning. And, we must decide if we want to use “splitter blades.” In the setup window for the main impeller dimensions, we have to set the tip clearance between the blade tip and casing. In this example, we will make an unshrouded, single-stage radial compressor. Next, we add a new component, choosing the radial mixed-flow impeller option. You’ll see the specific speed and the general machine type on the right side of the window. The integral part of the CFturbo software is the CoolProp-database containing fluid properties of numerous gases, liquids, and mixtures.Īdditional to the duty point, the inlet boundary conditions – inlet pressure and inlet temperature – must be defined. In this case, the fluid is Air at 20 degrees Celsius.īesides the ideal gas model, different real gas models are available, like Peng-Robinson or Redlich- Kwong. The design point, or duty point, is defined by mass flow rate, total pressure difference or total pressure ratio, and the rotational speed.
CFturbo aims to reach the best efficiency point (BEP) for the design point. In the “Global setup” window, We specify the design point of the compressor. The application is a so-called “High-Speed Turbo Blower” as used for wastewater aeration.įirst, we create a new project choosing the Compressor design module. In this video, we’ll show an aerodynamic centrifugal compressor design.
