One of the most popular kinds of these plasma thrusters are Inductively Coupled Plasma (ICP) torches. They have a high performance and a distinctive operation in both efficiency and power-to-mass ratio. In this paper, an ICP plasma thruster operation is simulated under the atmospheric pressure by using MHD models and FlexPDE (Partial Deferential Equation) software. Finally, having assumed steady state conditions, we have discretized linear equations. According to the initial and boundary conditions of the system, we have determined radial and axial velocity of the particles, the power dissipated, temperature, pressure, flow, flow driving force (thrust) as well specific impulse in each grid cell. To have a comprehensive study, the effect of the current source frequency and working gas flow rate on the thrust a...

Determination of the physical and chemical properties of red lentil seed showed that the physical properties of red lentil were significantly affected by moisture content. The red lentil seeds were especially rich in protein (25.9%) and starch (40.51%). The amount of K, P, Ca and Na were 1 024, 341, 170.3 and 65 mg 100 g -1 of dry matter, respectively. The major fatty acids in the red lentil oil were linoleic, followed by oleic, palmitic and linolenic acids. K e y w o r d s: lentil seeds, physical properties, nutritional properties, post-harvest processing
