CFD is an important R&D capability of INFINAIR’s Research Institute;; it is featured of high calculated result reliability and fast calculation process. By means of the all-series product utility module system, it can reduce the module development cost of new product at the same time of offering fast customization to customer, and ensure economy while realizing customization.
Successful cases of INFINAIR CFD technology:
1. INFINAIR product generally adopts CFD for systematic development and optimized design, and this is just why INFINAIR is capable of supplying more energy-saving and more efficient products with lower noise. Please see following picture of simulated aerodynamic performance process of INFINAIR complete mixed flow fan, a certain new box-type fan of INFINAIR and a certain centrifugal fan of INFINAIR.

——Numerical simulation technology CAE
1.Numerical simulation is a kind of application of Computer Aided Engineering (CAE), mainly includes two core technologies of CFD and FEA.
2.CFD is short for Computational Fluid Dynamics. CFD simulate-calculates the product performance inside computer, provides guidance for aerodynamic model design (optimize the number of blades, angles and widths) and noise prediction of fan, especially impeller, and thus helps the designer basically predict the final aerodynamic performance without producing so many prototypes, consequently realizes quick customized design or systemic optimization.
3.As a “virtual laboratory”, CFD can realize fast iteration, save cost and reduce R&D period, is a strong tool for effective and reliable fan R&D and non-standard customization, and will provide accurate scheme for optimization of ventilation system.
