In this paper, a novel fiber turbine flow sensor was proposed and demonstrated for liquid measurement with optical fiber, using light intensity modulation to measure the turbine rotational speed for converting to flow rate. The double-circle-coaxial (DCC) fiber probe was introduced in frequency measurement for the first time. Through the divided ratio of two rings light intensity, the interfere...

The modern internal combustion engine (ICE) has to meet several requirements. It be reliable with the reduced emission of pollutant gasses and low maintenance What is more, it efficient both at low-load high-load operating conditions. For this purpose, a variable turbine geometry (VTG) turbocharger used provide proper acceleration exhaust gases Such solution also In paper, result an unsteady, t...

following recent works of several authors like huilgol, bhattacharya etd. and javadpour et al., this paper is to contribute further to the literature of axial flow in a rotational coaxial rheometer. we consider axial flow of herschel bulkley mode1 between two concentric cylinders with the inner one rotating, while the outer cylinder is held stationary. an attempt has been made to direct the ana...

This paper presents a cold flow simulation study of a small gas turbine combustor performed using laboratory scale test rig. The main objective of this investigation is to obtain physical insight of the main vortex, responsible for the efficient mixing of fuel and air. Such models are necessary for predictions and optimization of real gas turbine combustors. Air swirler can control the combusto...

In stator–rotor interaction studies on axial turbines, the attention is commonly focused unsteady rotor aerodynamics resulting from periodic perturbations induced by stator flow structures. Conversely, less interest has been historically attracted regarding influence of released stator, correlated to propagation blade potential field upstream leading edge. this paper, experiments in research hi...

The type of turbine developed is based on the very low head of water potential source for the electric power production. The area of research is focused for the axial water turbine that can be applied at the simple site open channel with has a very low cost and environmental impact compared to the conventional hydro installation. High efficiency of axial turbine which applied to the very low po...
