Experimental observations revealed that the stagnant zone, which forms in the lower central part of a blast furnace, is an important feature of solid flow, and that it is affected strongly by gas flow. However, it is difficult to model this feature within the framework of continuum mechanics without empirical or arbitrary treatments. This paper reports the use of discrete particle simulation fo...

Gas assisted atomization is becoming increasingly important in many industrial applications such as physical, chemical and petroleum processes. In order to achieve proper atomization it is crucial to have proper mixing of gas (air) and liquid (water) in the feeding conduit before it enters into the nozzle. The flow regime, as well as the flow pattern and structure of the flow, are some of the i...

background and objective: reduced fat cheese often exhibits poor sensory quality due to the reduction of fat, which plays a critical role in flavor and texture. therefore, there is the challenge to produce a reduced fat cheese with improved sensory attributes and texture that is also comparable to its full-fat counterpart. the main objective of this research was to investigate the effect of dif...

For complex curved difficult-to-machine parts, a new method based on pneumatic suspension abrasive pool bright finishing processing is proposed, using the mixing of abrasive, workpiece surface, and fluidized to produce relative motion velocity, so that solid particles surface microscopic two-body wear achieve effect precision machining. The experimental test material widely used Q235 steel plat...
