This study aims to analyze the development of the boundary layer in fluid flow in a straight pipe. The boundary layer is a thin layer near the pipe wall that experiences the influence of intimidation, thus affecting the flow distribution velocity. The study was conducted numerically using CFD (Computational Fluid Dynamics) software by utilizing ANSYS Fluent to solve the Navier-Stokes equations. The fluid flow described is water with a variation of kece. The simulation results show that the boundary layer thickness increases with the length of the pipe due to the effects that occur on the wall. In addition, the velocity profile shows a transition from plug flow conditions near the inlet to a parabolic profile in laminar flow and a logarithmic profile in turbulent flow. These findings provide important insights in designing piping systems, especially in improving flow efficiency and minimizing pressure losses.
