SIMULATION OF DUST CAKE BUILD-UP ON THE FILTER MEDIUM This section describes a physical model for cake and pressure build-up on candle filters. The model was aimed at investigating filtration operation and reverse pulse cleaning of the filter. It is useful to calculate the filter cake thickness and pressure drop along the filter candle. Figure 1 shows the schematic diagram of filter cake build-...

Plastic shrinkage cracking is a problem for the service life, aesthetics and durability of concrete members. It occurs when tensile stresses are induced in fresh concrete, through plastic that restrained. caused by negative capillary pressure build-up, but can be controlled to prevent shrinkage. In this paper, control using high-capacity sensors explored. The behaviour self-compacting mix desig...

This paper presents a new modelling approach for liquid lubricant behavior in metal forming operations by focusing on the hydrodynamic pressure build-up micro pockets. Theoretical and numerical fundamentals of proposed are introduced, upsetting an aluminum cylinder with artificial pocket is presented as validation case. The framework splits fluid-solid interaction model into computational fluid...
