The present investigation simulates numerically the question of the rotating effects to the fluid transportation and flow field in a capillary tube. The efficiency of coating effects is represented by the effective film thickness, that is the fraction of original fluid left to cover the wall of tube. Better coating efficiency of injecting fluid is found at stronger rotating effects. Coating efficiency also depends strongly on viscosity ratio of the two fluids. Higher viscosity difference tends to resist the outward transportation of injecting fluid, thus worse coating effects. The inlet conditions are found not affecting the global features near the mixing front significantly.
