Case Study on CFD investigation of dense phase pneumatic conveying at a pipeline enlargement

Pneumatic conveying is being widely used by industry for their conveying system and the most critical problem that the system has is the corrosion of the pipeline. Some of the many engineers has develop a solution order to reduce the corrosion rate of the pipeline that is to increase the diameter of...
