The pneumatic conveying process of fine particles through filters was studied by CFD-DEM simulation method. porous media model and structure were used to simulate the airflow state blocking effect when they flowed filter. Under different particle feed rates initial velocities, effects plugging rate settling velocity in pleated analyzed, deposition height on fluid zone studied. results showed th...

Dense phase pneumatic conveying is widely used to transport granular materials or powder due to its efficiencies gained on cost and abrasion and erosion. To date these systems have been designed and analyzed using average frictional representation for the conveyed plug. This study explores the effect of this friction force by measuring strains on the pipe wall when the plug is moving passed the...

Computational Fluid Dynamics is now a new ramification of the numerical discretization method based on high-performance electronic computers, which focuses on fluid mechanics simulation. Fluid mechanics has two main braches that one is theoretical analysis and another is experimental research. Therefore, theoretical and experimental fluid mechanics were created as most important constituents in...

Cross-sectional measurement of particle velocity and concentration in a pneumatic conveying pipe is desirable for the characterisation flow dynamics determination mass rate. In this study, an inner-inserted electrostatic sensor array consisting nine pairs electrodes implemented to measure cross-sectional profiling particles over whole cross section square-shaped pipe. Experimental tests were co...

In order to communicate with a PLC (Programmable Logic Controller) flexibly and freely, a data communication model based on the PLC's free port is designed. In the structure of the model, a distributed data communication environment is constructed by using Ethernet and serial adapters. In the communication algorithm, a method of queuebuffer for multi-threaded is used to improve the real-time of...
