  • Method of generating precisely-defined wall shearing stresses
    Patent number: 4973165
    Abstract: A method is provided to generate over a confined space precisely defined distributions of the magnitude of the wall shearing stresses in a substrate/fluid boundary layer. A fluid flow is rotated around a center axis in the confined space. Simultaneously a defined fluid volume is removed in the rotational axis of the flow per unit time and recirculated or replenished through return openings in the lid or sidewall.
    Type: Grant
