Air Guard CFD Fluid Analysis Capabilities

CFD, short for Computational Fluid Dynamics, is a simulation technology that virtually conducts experiments on fluid flow situations by solving differential equations that control fluid flow numerically. Its basic principle is to discretely distribute the flow field of fluid flow on a continuous domain by solving the differential equations that control fluid flow, thus approximating the simulation of fluid flow situations.

While developing new air purification products, engineers of Air Guard first use professional engineering software to build a 3D model of the product structure and define various standard technical requirements in the component library. After processing the product structure, they transfer it to CFD software, define the calculation method, and conduct CFD simulation analysis on the air conditioning inlet section. This can simulate the pressure drop performance of the air purification filter, the flow field and pressure field changes when gas passes through it, and establish a reliable model. By optimizing the design based on simulation results, they can significantly shorten the project development cycle and quickly and accurately design air purification products that meet customer performance requirements. They also assist customers in discovering the real reasons that affect various performance indicators during the product design process, thereby providing a complete air purification product solution.
