Abstract: Flame speeds are important flame characteristics in combustion processes as it determines the stability of the flame. Accurate experimental measurements of flame speeds require optical systems and diagnostic instruments, such as those in schlieren photography. However, these systems are more suitable in laboratory environments. In industrial furnaces, simpler methods are required to determine the flame speeds for comparison. Infrared cameras are used to detect ‘hot spots’ in furnaces, and since the radiation intensity of the flame is indicated by the brightness of the pixels in the images, a sequence of images can be used to determine the difference in the pixels’ brightness, allowing determination of the flame’s movement and subsequently the flame speed. Thus, in this study, a tool to determine the flame speeds using an image processing technique is presented. Preliminary results of the flame speeds from a 150 kWth coal fired combustion test rig were obtained. The combustion test rig

Abstract: he fiber-reinforced composite materials supersede the metals in innumerable domestic and commercial applications like automotive and aerospace industries because of its advantages like high strength to weight ratio, better mechanical properties, durability, impact resistance and most important the corrosion resistance properties. But the machining of these heterogeneous type of materials is serious apprehensions because most of the FRP manufacturers do not provide standard procedure to machine these type of materials. Delamination is considered the major defect in machining of the FRP materials. Glass fibre-reinforced polymer (GFRP) composite materials are one of the important materials and are economic alternative to engineering and other FRP materials. In this study the abrasive waterjet machining of GFRP material is studied. The abrasive waterjet machining (AWJM) is one of the advance machining process of material removal in which high velocity abrasive particles are used to remove
