Exploration of Diffusion Welding of AISI 304 Stainless Steel Plates

Diffusion bonding method is an alternate method to join similar and dissimilar materials with minimum dimensional tolerance. It is one of solid state process in which two metallic surfaces are made to contact at the elevated temperature and pressure. Diffusion bonding process provides elevated quality joints without post weld machining. The main process parameters of diffusion bonding include temperature, pressure and holding time. In diffusion bonding technique microstructural changes were fashioned in the base metal which determines the mechanical properties of the bond at the boundary. Diffusion bonding method can be used to weld the dissimilar materials with different chemical and mechanical properties. The present work determines the control of process parameters on diffusion bonded joints of AISI 304 stainless steel plates. Experimental investigation on the microhardness, lap shear test were made for diffusion bonded couples and outcome are summarized.

Performance of Mixing Efficiency and RTD of Static Mixer in Liquid-Liquid And Gas-Liquid Mixture

Abstract- In this experimental work, the mixing efficiencies of immiscible fluids were studied with finding out the mixing index of the fluids at the different velocities and with different Reynolds’s number. For finding the efficiencies of the immiscible fluids the pressure drop acts as an important role so as the pressure drop increases then the mixing efficiency of fluids increases. Also, pressure drop directly effects on to know the increasing the mixing efficiency. Also, residence time distribution is the key factor which is found in the mixing of the immiscible fluids in the static mixer which shows the time which remains in the static mixer to pass out the solution which is also important for the calculating the mixing efficiency of the fluids. The objective of the study is to design the static mixer for estimating the maximum mixing efficiency of immiscible fluids.

Reduction of VR Using Pi and FLC in a Buck-Boost Converter by Combining SR Buck – KY Boost Converter

In this paper, an analyze and describe step by step process of designing, feedback control and MATLAB simulation of a voltage bucking-boosting converter by combining KY and Synchronous Buck converter for power battery applications. Unlike the traditional buck-boost converter [1, 2, 10, 11], this converter has only the positive output voltage, different from the negative output voltage of the traditional inverting buck-boost converter. This converter operates only in continuous conduction mode. The output current is the non-pulsating waveform thereby not only the current stress on the output capacitor is reduced but also reducing the output voltage ripples. By Combining the KY converter with the synchronous buck converter, a positive buck-boost converter is obtained and uses the same power switches with no right-half-plane zero. So that the circuit is made to be compact and the corresponding cost to below.
