The Numerical Simulation of Flow Characteristics in T-type Pipe

The manifolds are flow distribution devices commonly used in the heating furnaces, heat exchangers, reactors, boilers, and so on. The flow distribution uniformity in the manifolds, to a large extent, decides the operation safety and economy of these devices. Manifolds are consisted of a number of T-type pipes, the flow characteristics in the T-type pipe takes an important role in the flow distribution non-uniformity of manifolds, so flow characteristics in T-type pipes were systematically researched and analyzed by the Fluent simulation software in this paper, exploring the influencing factors such as the inlet mass flow rate on flow distribution non-uniformity, and providing some measures to improve the flow distribution uniformity.
