“…In reference 3, ansys-cfx17.0 was used to simulate the flow field of the whole cooling system including the axial cooling fan, and the influence of the flow field around the blade on the efficiency of the fan was studied. The loss caused by air flow collision or separation is directly proportional to the circumferential velocity of each point of the blade except the blade tip [3]. In reference 4, the lattice Boltzmann method (LBM) was used to directly simulate the flow field and aerodynamic sound field around the axial flow fan, and the changes of the flow field and sound field caused by different operating points were studied.…”

Based on the CFD simulation of the axial flow fan for air conditioning, a flexible and fast deformation model of axial flow fan is established in this paper. The influence of different fan design parameters on the performance of axial flow fan under different working conditions, such as different speed, air volume and pressure, is studied. A set of intelligent optimization platform for axial flow fan is formed and the performance of a certain type of fan is optimized under the working condition of 22000m3/h flow rate.

The proper design and installation of systems that enable the efficient control and removal of smoke and hot gases in underground parking facilities are necessary for protecting the public and property in the event of a fire. This paper discusses how studies using Computational Fluid Dynamics (CFD) related to smoke venting have contributed to improving fire safety in underground parking facilities. As vehicle fire incidents continue to rise globally, particularly in regions with a high density of underground parking, the need for comprehensive measures to mitigate these incidents has become increasingly urgent. This paper examines the applicability of CFD as a tool to address the challenges of smoke control in underground car parks, including those caused by fires involving electric vehicles. CFD application under various fire scenarios and ventilation strategies allows for identifying more effective smoke removal solutions, improving the protection of occupants and property. However, despite the potential of CFD simulations to enhance fire safety and smoke exhaust efficiency in underground parking, it is important to recognize the limitations of these simulations, particularly in dealing with the complex challenges posed by electric vehicle fires.
