AbstractIn this thesis wavelet neural network were used to predict viscosity of the fluid mixture in a wide range oftemperature and pressure Wavelet neural networks WNN combing the properties of the wavelet transformand the advantages of Artificial Neural Networks ANNs have attracted great interest and become a populartool for various fields of mathematics and engineering Using this method with the inputs temperature density and molar fraction output viscosity was predicted kind of artificial neural network algorithm thatwas used the propagation error algorithm with the gradient descent algorithm this type of algorithm tahtalgorithms with supervisor observer is The activation functions of the wavelet nodes in the hidden layerare derived from a Morlet mother wavelet The results of the computational process with this type of artificialneural network algorithm with the results of equations in predicting viscosity of articles in a wide range ofpressure and temperature were compared Comparing these results showed that wavelet neural networksused have many power in prediction of viscosity and the ability to compete with methods using equations oftheoretical and experimental Other advantage use of artificial neural networks in addition predict betterresults for the viscosity of the fluid mixture is in solved need to provide potential models and complexcalculations to obtain the integral and in a word this networks with regard to high expansion they reduceneed to the complex equations can also used as a tool for simultaneous prediction thermodynamicsproperties Key Words Artificial Neural Networks ANNs Wavelet Neural Network WNN Prediction Viscosity Fluids Mixture Isfahan University of Technology Department of Chemistry Prediction Of Viscosity of Fluid Mixture Using Wavelet Neural Network WNN By Ali Hassanzadeh sureshjani
