The Laminar Flow Simulation of Variable Diameter GFRP Pipe with Transition Region
To investigate the variation rule of fluidic speed in variable diameter GFRP pipe with transition region when the liquid flows through the pipe, the FLOTRAN CFD module of the ANSYS finite element software is adopted to take the laminar flow analysis on 4 diversion pipes with transition region in this paper. The finite element analysis process is introduced in detail, and the velocity vector distribution of the 4 diversion pipes is got. As can be seen from the graph, the velocity of the liquid begins to become quick before the liquid reaches transition region, the velocity of the central liquid is the fastest when the fluid passes the transition zone, the closer the distance is away the wall, the slower the liquid flows, and the distribution is conical basically. 37 degree is recommended in the transition region and it can provide the reference for the turbulent analysis of variable diameter GFRP pipe with transition region.
