A flow chamber whose length and width are far larger than its own height was widely used to study cell's mechanical behavior in vitro , especially the cell's adhesion property. The paper analyzed the flow field of the flow chamber in detail, and gave the analytical expressions of the velocity, pressure and shear stress when the fluid flowed in and out the chamber through a small crevice. Then, full and clear discussion of flow field was made. Also the velocity field was measured by an Ultrasonic Doppler Velocity-metre. It was found that the experimental values coincided with the theoretical values. These results were important to study the cell's mechanical behavior in vitro . 相似文献
