Validation of the Gnielinski correlation for evaluation of heat transfer coefficient of enhanced tubes by non-linear regression model: An experimental study of absorption refrigeration system

International Communications in Heat and Mass Transfer, 2020
Abstract The Wilson plot method has widely used to determine general heat transfer correlations, but this technique needs considerable experimental data. The Gnielinski correlation, however, simplifies the evaluation of the inside heat transfer coefficient of heating tubes only by using friction factor and hydraulic diameter. Nowadays, enhanced tubes,

Identification of heat transfer coefficient through linearization: explicit solution and approximation

Inverse Problems, 2017
An ill-posed problem estimating the heat transfer coefficient in coiled tubes from temperature data at the external tube is investigated. A singular value expansion of heat flux distribution is carried out for the case of noise free data and a smoothing method is developed to calculate the stable solutions for the noisy data. Regularization is achieved

Heat transfer coefficient calculated using a linear pressure gradient assumption and measurement for flow boiling in microchannels

International Journal of Heat and Mass Transfer, 2014
Abstract To obtain local flow boiling heat transfer coefficients, some studies used a linear pressure gradient method. In this study, this method is compared with a pressure gradient measurement method. The measurement was carried out for flow boiling of de-ionized water in single horizontal microchannels.

Determination of the interfacial heat transfer coefficient h in unidirectional heat flow by Beck's non linear estimation procedure

International Communications in Heat and Mass Transfer, 1996
Abstract In the numerical simulation of casting solidification, the thermal behavior of the casting/mold interface is characterized by the interfacial heat transfer coefficient, ‘h’. The determination of h is difficult as it involves the solution of the Inverse Heat Conduction Problem (IHCP).

A series solution of the non-linear fin problem with temperature-dependent thermal conductivity and heat transfer coefficient

Journal of Physics D: Applied Physics, 2007
An approximate analytical solution of the nonlinear straight fin problem is proposed. It is assumed that the heat transfer coefficient and the thermal conductivity are arbitrary functions dependent on the temperature. The approximate solution is obtained by linearizing the fin equation about an arbitrary reference temperature and then the linearized ...

Calculation of the residual stress of a 45 steel cylinder with a non-linear surface heat-transfer coefficient including phase transformation during quenching

Journal of Materials Processing Technology, 1999
Abstract From the TTT diagram of 45 steel, the CCT diagram was simulated by mathematical transformation, and the volume fraction of the constituents austenite, perisite, bainite and martensite in continuous cooling was calculated. The thermal physical and mechanical properties were treated as functions of the temperature and the volume fraction of ...
