Developing genetic algorithm-based neural networks and sensitivity analysis for thermal conductivity of natural gases

R. Beigzadeh; R. Ozairy

Volume 17, Issue 2 , June 2020, , Pages 44-55


  The artificial neural network (ANN) approach was applied to develop simple correlations for predicting the thermal conductivity of nitrogen-methane and carbon dioxide-methane mixtures. The genetic algorithm method was used to obtain global optimum parameters (weights and biases) of the ANNs. The methane ...  Read More

Computational fluid dynamics study and GA modeling approach of the bend angle effect on thermal-hydraulic characteristics in zigzag channels

S. Salimi; R. Beigzadeh

Volume 16, Issue 3 , September 2019, , Pages 70-83

  In the study, the thermal-hydraulic performance of the zigzag channels with circular cross-section was analyzed by Computational Fluid Dynamics (CFD). The standard K-Ꜫ turbulent scalable wall functions were used for modeling. The wall temperature was assumed constant 353 K and water was used as the ...  Read More

Prediction of the Effect of Polymer Membrane Composition in a Dry Air Humidification Process via Neural Network Modeling

M. Fakhroleslam; A. Samimi; S.A. Mousavi; R. Rezaei

Volume 13, Issue 1 , January 2016, , Pages 73-83

  Utilization of membrane humidifiers is one of the methods commonly used to humidify reactant gases in polymer electrolyte membrane fuel cells (PEMFC). In this study, polymeric porous membranes with different compositions were prepared to be used in a membrane humidifier module and were employed in a ...  Read More

Determination of the Equilibrium Parameters of Gaseous Detonations Using a Genetic Algorithm
Volume 5, Issue 3 , July 2008, , Pages 3-13

  The present work is concerned with the development of a new algorithm for determination of the equilibrium composition of gaseous detonations. The elements balance equations, and the second law of thermodynamics (i.e., the minimization of the Gibbs free energy of products), are used to determine the ...  Read More

Multi-objective Genetic Optimization of Ethane Thermal Cracking Reactor
Volume 5, Issue 3 , July 2008, , Pages 29-39

  An industrial ethane thermal cracking reactor was modeled assuming a molecular mechanism for the reaction kinetics coupled with material, energy, and momentum balances of the reactant-product flow along the reactor. To carry out the multi-objective optimization for two objectives such as conversion and ...  Read More
