Measurement of the Squish Flow in an Engine Cylinder Using a Laser -Doppler Velocimeter

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...

Measurement of Reynolds Stress Distribution in a Fluidic Element by the Laser Doppler Velocimeter

The one-phase flow and the two-phase flow in a fluidic element are investigated by measuring Reynolds stress distributions of the main jets using the laser Doppler velocimeter. In the one-phase flow, a water flow jets from a main nozzle into water and in the two-phase flow, a water fiow jets into air. Some results with the one-phase flow are as follows. When either of the two control ports is c...

An Experimental Investigation of Vortex Rings and Helicopter Rotor Wakes Using a Laser Doppler Velocimeter

Development of an in-cylinder processes model of a CVVT gasoline engine using artificial neural network

Today, employing model based design approach in powertrain development is being paid more attention. Precise, meanwhile fast to run models are required for applying model based techniques in powertrain control design and engine calibration. In this paper, an in-cylinder process model of a CVVT gasoline engine is developed to be employed in extended mean valve control oriented model and also mod...

A Study of Air Flow in an Engine Cylinder

A &etroke-cycle test engine was equipped m“th a glass cylinder an-d the air rnocements within it were studied wht% the engine was being motored. Dij$erent typee of air @w were produced by ueing shrouded intake valves in various arrangements and by altering the 8hape of the intake4r pawage in the qdinder head. The air movement8 were made visible by miz-ingfeather8 with the entering air, and high...
