Fluid friction short definition
WebDimples are small concavities imprinted on a flat surface, known to affect heat transfer and also flow separation and aerodynamic drag on bluff bodies when acting as a standard roughness. Recently, dimples have been proposed as a roughness pattern that is capable of reducing the turbulent drag of a flat plate by providing a reduction of skin friction that … WebThe principal characteristics of radiometers intended for the measurement of short-wave radiation m a y be listed as follows (not necessarily in order of importance): (a) long-term stability, with good short-term repro- ducibility, preferably over several years; (b) relatively good degree of adherence to the Lambert cosine law (i.e., for ...
