Micromachined two dimensional resistor arrays for determination of gas parameters [PDF]

, 2003
A resistive sensor array is presented for two dimensional temperature distribution measurements in a micromachined flow channel. This allows simultaneous measurement of flow velocity and fluid parameters, like thermal conductivity, diffusion coefficient ...

Effects of contraction ratio on loss reduction of the flow in the reducing elbow duct with a weir-shaped obstacle

Journal of Fluid Science and Technology, 2023
90-degree elbow pipe/duct is one of the piping element which is used frequently in industrial apparatus. The separated flow which occurs at inner corner of elbow part and the secondary flow which occurs at the elbow and its downstream cause significant ...

The pressure moments for two rigid spheres in low-Reynolds-number flow [PDF]

, 1993
The pressure moment of a rigid particle is defined to be the trace of the first moment of the surface stress acting on the particle. A Faxén law for the pressure moment of one spherical particle in a general low-Reynolds-number flow is found in terms of ...

Determination of Skin Friction Factor in Gravel Bed Rivers: Considering the Effect of Large-Scale Topographic Forms in Non-Uniform Flows

Hydrology, 2022
Determination of skin friction factor has been a controversial topic, particularly in gravel-bed rivers where total flow resistance is influenced by the existence of small-scale skin roughness and large-scale topographic forms.

Experimental Studies on the Critical Reynolds Number in the Flow of a Microencapsulated Phase Change Material Slurry

Energies
The disadvantage of phase change materials (PCMs) that store thermal energy is their low thermal conductivity. The macro-, micro-, and nanoencapsulation of PCMs are some of the ways to eliminate this drawback.

Hydrodynamic electron flow in high-mobility wires

, 1994
Hydrodynamic electron flow is experimentally observed in the differential resistance of electrostatically defined wires in the two-dimensional electron gas in (Al,Ga)As heterostructures. In these experiments current heating is used to induce a controlled
