Design and Optimization of a Spiral-Tube Instantaneous Water Heater Using Response Surface Methodology

Water, Journal Year: 2023, Volume and Issue: 15(8), P. 1458 - 1458

Published: April 8, 2023

In this paper, the fabrication and optimization of a spiral-tube heat exchanger (STHE) were considered for improving transfer rate efficiency traditional instantaneous water heaters. The large number heaters exported from customers “Garman Gas Toos” company, which was mainly due to corrosion leakage, imposed lot cost credit reduction company. high energy consumption second reason that justified working on new STHE. main innovation research is design construction with smaller size higher help identifying factors affecting its rate. order optimize responses, three variables considered, including fin (per unit area), exhaust outlet diameter, flow Implementing face-centered central composite (CCD), proposed levels corresponding response measured in laboratory. Using experiments (DoE), effects their mutual interaction evaluated. Response surface methodology (RSM) devised build prediction model obtain values responses optimal. Based results, optimum conditions STHE found be an diameter 4 cm 6 L/min coupled six fins. At optimal point, rate, as variables, obtained 85% 8480 W, respectively.

Effect of lubricating oil on non-azeotropic refrigerant in flow boiling: an entropy generation analysis

International Journal of Green Energy, Journal Year: 2024, Volume and Issue: 21(9), P. 2128 - 2141

Published: Jan. 17, 2024

Entropy generation analysis is a useful method for studying the relationship between heat transfer and pressure drop in flow boiling. The boiling process an actual refrigeration system inevitably affected by oil. Therefore, effect of oil on entropy needs to be investigated. A new non-azeotropic ternary refrigerant mixture, R447A, was selected as working fluid. Subsequently, models R447A with without were established. effects individual parameters per unit tube length under different conditions proposed benchmark comparison. results show that there optimal mass flux corresponding minimum at specific concentration, decreases increasing concentration. diameter also affects fluid oil, which increases decreasing smaller than same tube. When concentration 0–4.95%, total exhibits trend. within scope this research, addition beneficial reducing exchangers.

Numerical investigation of laminar heat transfer and fluid flow characteristics of Al₂O₃ nanofluid in a double tube heat exchanger

International Journal of Numerical Methods for Heat &amp Fluid Flow, Journal Year: 2023, Volume and Issue: 33(12), P. 3994 - 4014

Published: Sept. 4, 2023

Purpose The purpose of the study is to numerically investigate characteristics laminar heat transfer and fluid flow in a double tube exchanger (DTHE) using water-aluminum oxide (Al 2 O 3 ) nanofluid. examines effects nanofluid both counter parallel configurations. Furthermore, an exergy analysis conducted assess impact on destruction. Design/methodology/approach single-phase method has been used for Al nanoparticles water as base regime Reynolds numbers from 400 2,000. nanoparticle volume fractions (0 0.1), Nusselt number, coefficient, pressure drop, performance evaluation criteria (PEC) direction have studied. Findings findings indicate that incorporation into enhances rate DTHE. This enhancement attributed improved thermal properties working its boundary layer. PEC increase by approximately 19.5%, 58% 1.2, respectively, comparison pure water. Conversely, drop experiences 5.3 times relative Exergy reveals nanofluids exhibit lower destruction compared showed better agreement with experimental results two-phase method. Originality/value Dimensionless correlations were derived validated numerical number configurations based fraction high accuracy predict DTHE without performing time-consuming simulations. Also, was performed compare between
