The personalized models, based on advanced mathematical modeling of the human body and lung geometry, can be used to predict how aerosols will be inhaled, deposited on airway walls, and absorbed and cleared by lung physiology.

The focus of the design was to minimize the hydrodynamic loss generation, particularly in the diffuser channels.

The effectiveness of a ventilation system can be influenced by the uniformity of flow through the entire HVAC system, starting with the supply fan, through the ductwork to building loads, and to the exhaust fan. Although the result is typically a decrease in HVAC performance or vibration concerns, the worst case scenario is equipment failure. CFD modeling during the design phase can optimize performance.

Pumped storage power stations are experiencing rapid development in China with the increasing development of smart grid and extensive development of nuclear and wind power stations for renewable energy. As a key component of the mechanical part of pumped storage power stations, the reversible pump-turbine has the function of water pumping and electricity generation as the load varies in the electricity grid.

The aim of this paper is to apply 3D inverse design method coupled with multiobjective/multi-point automatic optimization method to design a low loaded axial fan.
