The flow inside the bending pipe conduit has been researched for a long time. But, there are few researches concerning the flow inside the passage in the rotating duct. In this investigation, three-dimensional flow analysis is performed in the curved duct with rotation. In this work, fluid is treated as incompressible flow, so Poisson equation for the pressure should be solved. The residual cut method is employed to solve the Poisson equation. In the time integration, the Adams Bashforth method applied to the convective terms and the Crank-Nicolson method applied for the viscous terms. As a result of this investigation, constitution of the secondary flow by curvature and Coriolis force became clear.
