A Review on Deviation Function Method
Abstract: This review paper covers the method to develop a lobe rotor pair profile used in many mechanical mechanisms. Lobe rotor pairs are conjugate generated pairs. It means that for each lobe there exists a corresponding another lobe such that for each point on first lobe there is a point on another lobe having same velocity. Deviation function method is widely used to develop a lobe profile. Deviation function method is …

Experimental Set Up of Optical Tomography Probe and Visualization of Characteristics of a Taylor Bubble
Abstract: Abstract Conventional methods for the detection of bubbles uses probes which physically protrude into the flow field and thus may affect the flow dynamics, thereby tethering the formation, development and flow of bubbles. In thermal power plant, it is rather difficult to physically see which type of two phase flow is happening in the pipe. In such a case, an optical tomography sees its application.
