"In plane geometry, a shear mapping is a linear map that displaces each point in a fixed direction, by an amount proportional to its signed distance from the line that is parallel to that direction and goes through the origin. This type of mapping is also called shear transformation, transvection, or just shearing. An example is the mapping that takes any point with coordinates to the point . I… " - Linear shear

NettetThis section provides a brief overview of the state of the art of the lift force acting on clean bubbles in linear shear flows. We begin with presenting the governing parameters of the problem and then introduce and describe the different lift force mechanisms identified in previous works. Shear stress (often denoted by τ (Greek: tau)) is the component of stress coplanar with a material cross section. It arises from the shear force, the component of force vector parallel to the material cross section.
