Design and Analysis of Helical Baffled Shell and Tube Heat Exchanger Using Numerical Method 2020-28-0362

The ideology behind the project is to change the helical angle of the baffles that are attached to the heat exchanger so that it increases the flow rate of high viscous fluids. Thermo-water powered effectiveness examinations were done on five trisection helical confound heat exchangers with unmistakable tendency edges, puzzle shapes or contact examples, and one segmental astound heat exchanger (SEG). Examinations of thermo-water powered in general execution were performed on five trisection helical perplex warmness heat exchangers with exceptional tendency edges, confound shapes or association examples, and one segmental puzzle warmness heat exchanger (SEG). A relative assessment of three regions bewilder plans with tendency edges of 10 degree (10°S), 15 degree (15°S), and 20 degree (20°S); an oval confound conspire with a tendency edge of 15 degrees (15°E), and a hub cover area perplex plot with a tendency edge of 20 degrees (20°D) become executed. Nearby pictures had been built to procure pressure misfortune qualities and stream territory dispersions. The stream region qualities, which incorporates the Dean vortex optional stream and sidestep spillage between contiguous puzzles, are demonstrated and referenced. The indistinguishable tendency edge plans have unmistakable properties because of the perplex shapes or association designs. The general execution of the start to finish conspire is better than that of the pivotal cover plot, and the oval confuse plot is the second rate compared to the field perplex plot. The 20°S plan has the ideal complete record and most reduced shell-side weight misfortune. The 10 °S plan does have the best shell-side Nusselt number and shell-side weight misfortune, and can best be selected through heat movement efficiency in a designing application that may be extremely simple.
