Strainer is placed in front of the machinery and the middle or end portion of a pipe for preventing the entry of suspended solids and the residue is the inflow through seawater. Filter is installed in the Strainer inside with mesh. It removes the particles contained in the oil that is attached to the auxiliary engines and engines for ships, and is sucked into the pump to remove particles, such as thick sludge and foreign matter. The most important portion of the functional aspect is cross-sectional area of filtration, has filter porosity.
First, the strainer is the resistance of fluid transported from the point of view of accessories of the tube. In other words, fluid that has passed through the strainer will consequently occur the pressure drop.
Further, for receiving the pressure of the structure by the fluid resistance, Strainer constructed in the form of filter mesh must also be considered in the structural stability. Therefore, evaluation of the pressure loss is a parameter Filter shape optimal considering the transport capacity of the fluid in the plane processors of the design is carried out, structural stability in a use environment should be evaluated.
If you want to apply the purpose of the development and production of Strainer size of various shapes and the development process of such a series, it is to take time and cost a lot.
Therefore, to verify the validity of the design in the basic design of the product, as well as reduce the trial and error shape design of the prototype, in material selection, the prototype was produced in detailed design later, numerical simulation, evaluation on a trial basis it is possible to perform an evaluation on the matters that can not be, and to provide a material for mass production.
The Filter of Strainer, a number of hole are formed at regular intervals, interpretation resources and an increase in analysis time of the entire request overly To do numerical analysis by configuring a grid of all the hole of these There is a drawback to be, interpreted and executed is practically impossible to. Perform flow analysis using Porous Domain numerically analytically for the numerical analysis of the fluid passing through the perforated plate thereof, the characteristics of differential pressure and hydrodynamic properties of the mesh size of the filter under the same flow conditions consider.
