.... The other technique enables sensor-based measurements of the wall shear stress magnitude and direction. Both techniques are based on the close link between momentum and heat transport in the boundary layer and correlate the surface temperature distribution of a heated surface (first technique) or a heated...

... is encountered in condensation particle sensors where nanoscale particles grow to micrometer size and can be measured optically. To develop condensation particle sensors that are miniscale and highly portable, we have computationally modeled the flow, heat, and mass transfer in a minichannel and determined...
