Abstract The solvent diffusivity is considered as a key factor in the design of solvent assisted processes in the bitumen field. In this study, a novel Adaptive neuro-fuzzy interference system (ANFIS) is employed to evaluate the diffusivity of the light hydrocarbons in the bitumen system. The particle swarm optimization (PSO) and genetic algorithm (GA) are adopted to promote ANFIS efficiency. The proposed models are established by a prepared dataset from multiple papers in the literature. Temperature (T), pressure (P) and molecular weight of alkanes (Mw) were considered as the input variables and on the other hand, Statistical parameters and graphical methods were used to appraise ANFIS, ANFIS-PSO, and ANFIS-GA performance. The results demonstrated that the highest correlation coefficient is related to ANFIS-PSO with R2 = 0.991 and 0.987 for train and test data, respectively. In the end, the results indicated that the ANFIS-PSO model has a higher level of desirability based on statistical parameters.

Abstract The diffusion coefficient of gaseous solvent in bitumen is an essential parameter in numerical modeling of solvent-assisted thermal recovery processes. The reported measurements of solvent diffusion coefficient are relatively scarce, especially at the high temperature. In this study, a new constant-pressure experimental technique for one-dimensional diffusion tests, which accounts for the bitumen swelling and density change, was developed. A novel analytical model was used to interpret ...

Abstract One of the essential characteristics of diesel oils is their cetane number (CN) which indicates the ignition delay of the fuel in the process. In this study, using PSO-ANFIS technique, CNs of biodiesel and conventional diesel (called petrodiesel) oils were modeled and estimated based on the fatty acid methyl ester compositions of biodiesel oils and carbon type structure of the diesel fuels. For the first time, novel correlations were developed for the estimation of CNs of biodiesel and ...

The design and manufacture of highly efficient evaporators and heat exchangers in cooling machinery need an accurate estimation of the boiling heat transfer coefficient of the refrigerants. In the present study, the boiling heat transfer coefficients of different refrigerants were predicted using machine learning methods and were compared to the existing empirical correlations. For this purpose, four models of ANN, ANFIS, ELM and SVM were developed by using MATLAB functions. 320 data were collec...

Abstract Lifestyle development and increasing urbanisation and consumption of fossil fuels, monitoring and controlling air pollution have become more important. This study has used the available data of key pollutants to predict their future status through time-series modelling. Most researchers have employed Autoregressive Integrated Moving Average and Logistic Regression techniques, and Adaptive Neuro-Fuzzy Inference System has rarely been used to analyse time-series data. Traditional time-ser...

Abstract In this work, the density of biofuel is estimated using four intelligent models: a Least Square Support Vector Machine (LSSVM), a Radial Basis Function Artificial Neural Network (RBF-ANN), a Multi-layer Perceptron Artificial Neural Network (MLP-ANN), and an Adaptive Network-based Fuzzy Inference System (ANFIS). These models are used to estimate the density of biofuel based on intermolecular interactions and the van der Waals radii of the atoms. Various statistical analyses are performed...

Abstract One of the major properties of biodiesel fuels is cetane number (CN) which expresses the ignition characteristics and quality of motor power. The main idea of this work was proposing an accurate model for estimation of the cetane number of biodiesel in terms of fatty acid methyl esters composition. In doing so, least-square support vector machine (LSSVM) approach was coupled with Genetic algorithm (GA), particle swarm optimization (PSO) and hybrid of GA and PSO (HGAPSO) algorithms and a...

Abstract The relationship between flammability limits (FL) of gas mixtures and their molecular structures was studied in this research based on the quantitative structure-property relationship (QSPR) method. The genetic algorithm (GA) was used to select an optimal subset of descriptors which show a significant contribution to the properties. The external validation, which checking the stability and predictive capability of the obtained models, was focus of this study. Three different external va...

Ground vibration induced by rock blasting is one of the most crucial problems in surface mines and tunneling projects. Hence, accurate prediction of ground vibration is an important prerequisite in the minimization of its environmental impacts. This study proposes hybrid intelligent models to predict ground vibration using adaptive neuro-fuzzy inference system (ANFIS) optimized by particle swarm optimization (PSO) and genetic algorithms (GAs). To build prediction models using ANFIS, ANFIS–GA, an...
