A schematic diagram of DLR scramjet model [7-9] is described in Fig. 1.The air enters into combustion chamber at M=2.0 whereas hydrogen fuel (H2) is injected parallel to the air stream at M =1.0. The width and height of the combustor section at the entrance is 40 mm and 50 mm respectively which is then diverged at an angle of 3ο on the upper wall of the combustor. The strut is 32 mm long and 6mm height which are located at a distance of 77 mm from the entrance. The boundary conditions of Waidmann

The structure of this report analyses the discretization of meshes‚ showing difference in results subject to variable changes. The general findings show that the different contours and iterations produced become increasingly accurate as the grid value increase or the order of discretization increases. 2. Altering

clutch is splined and carries a gear that meshes with the largest lay shaft gear. The main shaft has a number of gears that mesh with the gears on the lay shaft‚ However‚ these gears being on bushes or ball/roller bearings are free to move on the main shaft without transmitting any torque. All the gears on the lay shaft are rigidly fixed with it. When the left-hand dog clutch is made to slide to the left by means of the gearshift lever‚ it meshes with the clutch gear and the top speed gear

FERRO CEMENT Introduction The term ferrocement is most commonly applied to a mixture of Portland cement and sand applied over layers of woven or expanded steel mesh and closely spaced small-diameter steel rods rebar. It can be used to form relatively thin‚ compound curved sheets to make hulls for boats‚ shell roofs‚ water tanks‚ etc. Ferro concrete has relatively good strength and resistance to impact. When used in house construction in developing countries‚ it can provide better resistance to

This paper will define laparoscopy in general‚ how a laparoscopic surgery is performed‚ the different types of laparoscopic instruments and the benefits and risks associated with undergoing a laparoscopic surgical procedure. Laparoscopic surgery has evolved rapidly in the last twenty years and as the field advances there are constant new innovations. Laparoscopy‚ also known as minimally invasive surgery or videoscopic surgery is an operation performed in the abdomen or pelvis through small incisions

is a stationary pen that traps fish in coastal fishing grounds. Traditionally‚ these techniques have provided small-scale fishermen and their families with a means of subsistence. Fishing nets are meshes usually formed by knotting a relatively thin thread. 2. Net fishing method - Fishing nets are meshes usually formed by knotting a relatively thin thread. Netting is the principal method of commercial fishing‚ though longlining‚ trolling‚ dredging and traps are also used. Other countries use the
