The second pair of air inlet holes provide air to the second fan, which expels that air through a nozzle. The nozzle restricts and directs the expelled air for a specific use such as an air pump or blower. The device for modifying air flow can be fitted with a cowl that collects and...
The air nozzle has a coupling element for the horizontal lamellas (4) in the form of a coupling rod (7) operated by an operating wheel (6) which has a projection (61) on the endface. The projection passes through an aperture (12) in the wall of the housing (1). It has a pivot...
4.3.2 Calculation procedure The procedure of the airflow network model is shown in Fig. 14. The pressure and airflow (mass) rate of the node are calculated in the airflow module. Then, the temperature and humidity of the node are decided on the building energy simulation side. Finally, ...

According to the gas lubrication theory, Timoshenko’s thin film theory and the simulation figure of the pressure distribution of the air film flow field, the air load distribution model of the air film is established, and the deformation expression of the large liquid crystal glass substrate in...
The unit has air conducting units formed as driven (5), driving and fixed (7) plates in air flow direction. The plates have bars between which the air flows through the plates. The plates are swiveled in the flow direction in such a way that the plates form inclined air conducting surfa...
measured the pressure when air flows through the main nozzle, calculated and analysed the line resistance and local resistance which caused the flow pressure drop, and fund that local resistance is the main reason of nozzle's energy consumption, the structure of the main nozzle should be improved...
An alginate solution extruded through the nozzle was sheared by the airflow. The resulting alginate droplets fell directly into a CaCl2 solution, and calcium alginate beads were formed. The device enabled us to successfully encapsulate living cells into 150 μm microcapsules, as well as control ...
flow field of main nozzle of air-jet looms.Then,comparison has been made between the numerical and experimental values.Results show that FLUENT is a powerful and useful tool for the numerical simulation of the flow field of air-jet loom main nozzle,and this method is better than test method...
By contrast, Models 3 and 4 provided complex meshes that complicate the convergence of the calculation and require a suitable treatment of both the viscosity and the flow near the walls. Model 3 showed the smallest error (16%) in the air velocity estimated in the treatment plane. Model 4 ...
