In the present study, an RE-1000 Free Piston Stirling Engine (FPSE) combined with a Permanent Magnet Linear Synchronous Machine (PMLSM) was analyzed. First, nonlinear thermodynamic model of FPSE developed and validated. Based on this model, gas temperatures pressures in different parts system also its thermal efficiency can be calculated. Then, PMLSM modeled. At next step, systems were combined...

For industrial design and the improvement of fluid flow simulations, computational dynamics (CFD) solvers offer practical functions conveniences. However, because iterative simulations demand lengthy computation times a considerable amount memory for sophisticated calculations, CFD are not economically viable. Such limitations overcome by data-driven learning models based on neural networks, wh...

The manoeuvring behaviour of a vessel in currents differs remarkably from its water without current, stemming hydrodynamic effects caused by the presence current. Given that vessels operating open seas and coastal waters are mostly exposed to ocean currents, it is important have an understanding influence on ship manoeuvrability. In present paper, means unsteady Reynolds-Averaged Naiver-Stokes ...

We investigate a regularity for weak solutions of the following generalized Leray equations \begin{equation*} (-\Delta)^{\alpha}V- \frac{2\alpha-1}{2\alpha}V+V\cdot\nabla V-\frac{1}{2\alpha}x\cdot \nabla V+\nabla P=0, \end{equation*} which arises from study self-similar to Naiver-Stokes in $\mathbb R^3$. Firstly, by making use vanishing viscosity and developing non-local effects fractional diff...

This study was based on a geochemical soil survey of Stoke-on-Trent in the UK 747 surface samples analysed for 53 elements. A subset 50 these were their bioaccessible As and Pb content using Unified Barge Method. Random Forest modelling, total element data as predictor variables, used to predict all samples. inverse distance weighed predictors bedrock superficial geology, also map both 400 × sp...
