Nusselt Number Measurement of Air Flow between Grooved Rotor and Stator of a Generator

In this article, turbulent flow heat transfer in the air gap between rotor and stator of a generator under nonhomogeneous heat flux is studied experimentally. The rotor consists of four symmetrical triangular grooves. The stator surface is smooth and does not include any grooves. The relative heat flux between the rotor and the stator is 1 to 3. Temperature and heat flux are measured locally at...

Flow rate measurement in modern ambient air samplers – how accurate ?

New generation ambient air samplers operate at much lower sampling flow rates than do their “high volume” predecessors, namely 16.7 liters/minute. When these new air samplers emerged several years ago there were limited tools available with which to assess and calibrate their operating flow rate. In 1996 a flow meter specifically designed for these new air samplers came available, known as the ...

Tissue blood flow measurement by laser Doppler technique

  Measurement of blood flow and the effects of different factors on tissue blood flow are important fields of research in physiology and pharmacology. So far, different methods have been innovated, using laser light is the Last one. In this article history, principles and specifications of laser technique along with its advantages and disadvantages ( in comparison with other methods) are revie...
