An efficient immersed boundary method for fluid flow simulations with moving boundaries
作者：
Highlights：
• We have developed an efficient immersed boundary (IB) treatment to simulate the interaction effect of fluid flow past a pair of circular cylinderswith heat transfer.
• A simple imputation approach was proposed and applied to the immersed grid, and the Dirichlet and Neumann boundary conditions were satisfied.
• High-resolution of local differential quadrature (LDQ) method is employed to discretize the Navier–Stokes equations.
• We used three parameters included the Re number (10 ≤ Re ≤ 200), transverse spacing (g* = L/D), and longitudinal spacing (s* = S/D)to evaluate the heat transfer effect under dissimilar flow conditions.
• The IB method and the discretization of the LDQ method were integrated to process and solve for complex IB problems involving heat transfer and flow–particles coupling.
