What are the design targets? The project involves the design and optimization of a high specific speed centrifugal pump stage. The optimized stage design should deliver the required head at a target efficiency of 90% with all the stage components and their roughness included while meeting the required suction performance (NPSHR) and axial thrust criteria ..read more

In the first part of this article, we showed how to perform the initial design of a radial inflow turbine rotor using the 3D inverse design method. In this second part, we demonstrate the use of Optima feature in TURBOdesign1 to rapidly optimize the initial rotor design to a less 3D blade (not completely radial-filament), and quickly obtain the desired trade-off between its aerodynamic and mechanical performance ..read more

Radial inflow turbines are used in a wide range of applications, from big geothermal power plants to small gas turbines and turbochargers for automotive engines. They are found suitable for several industries encompassing ship, aircraft and space power systems where compact sizes and high expansion ratios are required ..read more

In the first part of this article on the design of a wastewater pump, we showed that there is scope for improvement in the baseline impeller especially in terms of meeting the solid-handling requirement ..read more

TURBOdesign Suite is a unique aerodynamic and hydrodynamic 3D design software package that allows users to design, analyze and optimize all types of turbomachinery, such as axial, mixed-flow, or centrifugal pumps, compressors, fans, turbines and torque converters. Using the software, designers evaluate turbomachinery package size and performance predictions, perform detailed 3D blade design with 3D inverse design capabilities, analyze flow information per component, stage performances with turbomachinery specific 3D computational fluid dynamics (CFD), and automate exploration of the design sp ..read more

In the first part of this article on the design of a small-scale high speed centrifugal compressor for domestic heat pumps, we showed that the baseline impeller satisfies the basic requirements in terms of peak efficiency point and blade lean/bow parameters ..read more

Heat pumps are used to absorb heat from a cold space and transfer it to a warmer one, such as for ambient heating in case of air conditioners. For this, there is a need for a compression device which has traditionally been positive displacement machines for large scale industrial applications.  ..read more

In the first part of this article on the design of a Sirocco-type CPU cooling fan stage, we showed that there is scope for improvement in the baseline impeller especially in terms of achieving the stage pressure rise requirement ..read more

Central Processing Unit (CPU) is a critical component of any high performance computing machine and is used for highly demanding tasks such as creative production, machine learning, cryptocurrency mining and to render computer graphics for video games. But with great power comes the need for effective cooling, and therefore CPU cooling is a critical aspect that directly impacts the system performance and longevity. Its main goal is to maintain optimal operating temperatures to prevent overheating, which can otherwise lead to performance throttling, instability, and even permanent damage to th ..read more
