A modified Gaussian moment closure method for nonlinear stochastic differential equations

There are many physical phenomena in engineering applications that are mostly modeled as stochastic differential equations. Sensor noise and environmental disturbance are two main sources of randomness. Determination of a closed-form analytical solution for the dynamical systems under random excitation is significantly useful for further investigations of these systems ...

Esmaeilzadeh–Roshanfekr equation of state coupled with CPA model: Application in viscosity modeling

The present study aims to evaluate the performance of the cubic plus association model for the estimation of physical properties of associating fluids. In this regard, this model with different physical terms was evaluated. Soave–Redlich–Kwong, Peng–Robinson, Patel–Teja, and Esmaeilzadeh–Roshanfekr cubic equations were utilized as the physical contribution in the model. This was the first study to evaluate 3-parameter equations such as Patel–Teja and Esmaeilzadeh–Roshanfekr …

A numerical investigation on the heat and fluid flow of various nanofluids on a stretching sheet

Following the necessity of investigating fluid flow and heat transfer in the stretching sheet problem and effect of nanofluids on them, performance of various nanofluids were investigated in the present study. Three base fluids (deionized water, ethylene glycol, and engine oil) in combination with 18 nanoparticles (metals and their oxides) were investigated. While experimental methods are preferable, a mathematical model was developed and solved by applying differential quadrature method...

Numerical Modeling of Fluid Flow and Thermal Behavior of Different Nanofluids on a Rotating Disk

The thermal and velocity profiles of various nanofluid systems on a rotating disk are simulated. Finite difference method, the orthogonal collocation method, and the differential quadrature method (DQM) of numerical approaches are used to solve the governing equations and are compared to determine the faster and more accurate solution procedure. Five nanoparticles Al, Al2O3, Cu, CuO, and TiO2 solved in three base fluids water, ethylene glycol, and engine oil are considered to be used …

Light olefins/bio-gasoline production from biomass

Following energy concerns, global warming issues, and urgency of exploring new sustainable and renewable sources of energy, exploring new routes for the production of energy carriers and valuable chemicals is currently of a great interest. In this regard, the production of olefins and gasoline (aromatics) from biomass feedstocks is state of the art. Accordingly, probable routes for converting biomass/bio-oil feedstocks to olefins and gasoline (aromatics) were investigated in this study…

Hydrogen Production Through Pyrolysis

Growing worldwide consumption of energy during the last decades is an outcome of growing world’s population and also the strong dependence of human’s lifestyle to energy carriers. As an example, 20% of global energy consumption belongs to the transportation section. Although fossil hydrocarbon-based energy carriers opened new vistas within the procedures of energy production, decreasing sources of natural gas and crude oil is making the governments and industries explore alternatives …

Integration of microalgae into an existing biofuel industry

Finding alternative sources for renewable energy, which is technically feasible, easily available, and able to compete economically with fossil fuels, is an essential challenge in today's world. Microalgae, with high content of lipid, can be utilized for producing different biofuels in an economically impressive and environmentally sustainable way. Accordingly, various stages of fuel production from microalgae were reviewed in the current study…
