INFINAIR's Numerical Simulation Technology
INFINAIR owns the industry-leading CFD technology
INFINAIR Research Institute masters a set of core CFD technology combining theory with practice owned by INFINAIR itself. Through a large number of repeated engineering applications for many years, now, INFINAIR’s CFD capability is mature and accurate. Besides, in combination with internationally accredited precision laboratories, Our CFD processes have been repeated hundreds of times to allow for comparison between theoretical values and test results, accumulating valuable test data.
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.

2. With respect to garage ventilation system optimization, INFINAIR has successfully developed a new, complete series centrifugal inducing fan with high static pressure as wehll as far projection distance, and guide the ventilation system layout of underground garage of customer. The following is the flow field layout simulation of an underground garage.
INFINAIR has mature FEA technical capability
1.In the practice process of FEA technology for many years, INFINAIR has accumulated a large number of data and experience which are suitable for actual physical property of common materials in China market.
2.INFINAIR Research Institute fully calculates and repeatedly adjusts the material type, material thickness, structural form and processing way in design stage to ensure that the parts can resist various pressures in operation, ensure that the fan can operate reliably for a long time, and ensure that the product cost is reasonable.
3.The final product scheme goes through the reliability verification of INFINAIR laboratory, conducts failure analysis and life extension analysis for products suffered aging test, reaches a definite conclusion, and thus reasonably saves equipment investment while improving product reliability.

——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.
