Heat and Fluid Flow Analysis and ANN-Based Prediction of A Novel Spring Corrugated Tape

Abstract

A circular tube fitted with novel corrugated spring tape inserts has been investigated. Air was used as the working fluid. A thorough literature review has been done and this geometry has not been studied previously, neither experimentally nor theoretically. A novel experimental investigation of this enhanced geometry can, therefore, be treated as a new substantial contribution in the open literature. Three different spring ratio and depth ratio has been used in this study. Increase in thermal energy transport coefficient is noticed with increase in depth ratio. Corrugated spring tape shows promising results towards heat transfer enhancement. This geometry performs significantly better (60% to 75% increase in heat duty at constant pumping power and 20% to 31% reduction in pumping power at constant heat duty) than simple spring tape. This paper also presented a statistical analysis of the heat transfer and fluid flow by developing an artificial neural network (ANN)-based machine learning (ML) model. The model is evaluated to have an accuracy of 98.00% on unknown test data. These models will help the researchers working in heat transfer enhancement-based experiments to understand and predict the output. As a result, the time and cost of the experiments will reduce. The results of this investigation can be used in designing heat exchangers.

“…Souayeh et al tried to show the thermal performance of a circular tube fitted with corrugated spring tape inserts and highlights its potential for constructing heat exchangers. 36 The paper presents a statistical examination of heat transfer and fluid flow by constructing a machine learning model based on an artificial neural network which can help researchers understand and predict the output of heat transfer enhancement-based experiments. Skrypink et al presented a new artificial neural network model to estimate the friction factor and heat transfer coefficients for turbulent flow in tubes with inner helical finning.…”

Parametric CFD Thermal Performance Analysis of Full, Medium, Half and Short Length Dimple Solar Air Tube

“…In the literature, there have been many laboratory experiments on heat augmentation techniques that utilize twisted tape as a passive technique [4][5][6][7][8][9][10][11]. Following this, the CFD modelling methodology was developed as a strong and useful method for better understanding complicated hydrodynamics [12][13][14][15][16][17][18] in many industrial processes, thanks to developments in computer hardware and software and the resulting increase in calculation speed.…”
