Abstract

nIn present review, a shell and curled cylinder heat exchanger will be numerically considered. The creation technique for helically looped tube which contains turbulator and furthermore the impacts of turbulator on warm and frictional qualities of hotness exchanger will be introduced in this review. CFD examination on ANSYS FUENT programming will be acted in two principle modes. In first mode, the liquid of looped cylinder will be water and in second mode the liquid of wound cylinder will be air. Parallel and Counter Flow of the two different fluents are being studied. Every mode will be read up for both void looped tube and with turbulator under various liquid stream rates. The liquid of shell side will be high temp water for all cases. Researches shows that this sort of heat exchanger can be utilized in covered cylinders which fundamentally expanded the general hotness move coefficient and clearly pressure drop. Air is introduced inside the heat exchanger for better results. In summing up of the bubbles and the interaction with the heta/thermal boundary layer can increase the velocity (hence the Reynolds number) of the shell side flow.n

Abstract

nIt is a multipurpose farming mechanism that can aid in various farming processes. The processes involved in farming asks for tedious efforts and high manpower. Therefore, a machine that can streamline the entire process and significantly lower the demand for personnel is needed. The mechanisms of the machine peers over the traditional tools used as well as newer machines for individuals’ processes and tries to be better. The potential for robot-enhanced productivity in agriculture is enormous, and farms are seeing an increase in the presence of robots in various forms. Technology can probably solve the other issues connected to autonomous farm equipment. A swarm of little machines may be more effective and less expensive at producing crops than a few giant ones. Along with the mechanism, various channels will be attached that can aid in different farming activities. Thus, a mechanism that can combine various activities of farming in an effective and productive manner is designed and analyzed.n

Abstract

nIn this study, an experimental method for the selection of optimal welding for joining metals there are several methods which they are used for joining metals, that it includes using welding brazing, Metal Inert Gas (MIG) Welding and Gas Metal Arc Welding is an arc welding process, in which the weld is shielded by an external gas (Argon, helium, CO2, argon + Oxygen) or other gas mixtures is one of the widely used techniques for joining ferrous metal. (MIG) welding process offers several advantages like joining of unlike metals, low heat effected zone, absence of slag etc, Thus the welding condition has to be selected carefully. By studies, the quality of welded joints depend upon three important factors are: type of power supply (DCSP, DCRP or ACHF), type of inert gas used for shielding and type of material the welded joint. In this paper deals with the investigation of Tensile strength of welded buttly joints, by three types of welding (Brazing welding), (MIG welding) and (Steel rod welding). Where it was selected the steel for preparing the specimens and it was tested the tensile strength of the welded joints where tested by a universal tensile testing machine in laboratory and the results were evaluated, which it confirmed importance of tensile testing that have to determine whether butt welded joints fulfill all of the required standards before use and also it should be select the type of weld the suitable of the type of metal.n

Abstract

nOne of the most crucial parts of any drone is the frame. In this research, we use ANSYS topology optimization to optimize the frame design in order to lighten its weight. Drone frame design is geared to bear big loads while having a light frame. Consequently, less material will be used, and the drone’s performance will be enhanced. Due to its inherent advantage of deployment at the appropriate places, unmanned aerial systems, more often known as drones, have found important usage in the aerospace, strategic, and civil sectors. Drone utilisation is rising significantly over the world, especially for civil and defense operations, as a result of their many benefits. Drone development has become possible for a wide range of applications, thanks to technological breakthroughs in drone manufacturing, navigation, and control systems. UAVs are used for a variety of scientific and research purposes in a variety of settings, including the remote monitoring of wildlife and analysis of various environmental data. Extracting volume data from quarries, inspecting plants for precision agriculture, using communication antenna, and inspecting power lines are a few further applications.n
