This paper describes visualization of thrombus formation process on wall surface in Couette flows. The aim is to investigate the effect of shear stress or shear rate, especially constant shear rate in Couette flows, on the thrombus formation. In this investigation, by visualization of the thrombus formation in blood plasma flow, it was found that the flow rate and shear rate have strong effects on the thrombus formation rate. The thrombus formation rates in the Couette flows was obtained by special double cylindrical test rig. Effect of the different of coating and shear rate on thrombus formation rate was investigated. From these results, even if coating surface is changed, the relationship between the shear rate and Rs is same.
