A distributed resistance inverse method for flow obstacle identification from internal velocity measurements

Inverse Problems, 2021
Abstract We present a penalization parameter method for obstacle identification in an incompressible fluid flow for a modified version of the Oseen equations. The proposed method consists in adding a high resistance potential to the system such that some subset of its boundary support represents the obstacle.

Influence of obstacles in coal mine roadways on smoke flow characteristics

Gong-kuang zidonghua
Underground coal mine fires generate smoke that spreads along roadways, and its flow state is easily affected by internal obstacles, forming local smoke stagnation zones, increasing the accumulation risk of toxic gases, and seriously threatening the safe
