As a mesh-free method, smoothed particle hydrodynamics (SPH) has been widely used for modeling and simulating fluid–structure interaction (FSI) problems. While the kernel gradient correction (KGC) method is commonly applied in structural domains to enhance numerical consistency, high-order consistency corrections that preserve conservation remain underutilized fluid despite their critical role FSI analysis, especially multi-resolution scheme where solid are discretized with different spatial...

The construction process plays a key role in sustainable development of the environment. With concept being put forward world, some countries released green standards to strengthen requirements phase. Green code checking needs integrate semantic information embedded and model involved Industry Foundation Classes (IFC) and/or Model View Definition (MVD), which are generated separately lead difficulty integration for checking. At present, existing code-checking methods cannot be directly used...

Efficiently enhancing heat conduction through optimized distribution of a limited quantity high thermal conductivity material is paramount in cooling electronic devices and numerous other applications. This paper introduces target-driven all-at-once approach for PDE-constrained optimization derives splitting smoothed particle hydrodynamics (SPH) method optimizing the problems. In this method, iteration system split into several easily addressed steps. A targeting step employed to...

This study investigates the effects of wind shear and coefficients on near wake a turbine. A turbine is subjected to shear, which leads unsteady performance blade characteristics wake. Wind 0.1, 0.2, 0.3 are used. The results obtained using three-dimensional incompressible Reynolds-Averaged Navier-Stokes equations, turbulence, simulated via shear-stress transport k–ω turbulence model. flow air and, in particular, axial velocity tangential strongly affected by rotation region There an obvious...

This paper presents analysis methods for improving the electromagnetic characteristics of a high-speed electrical multiple unit (EMU) train with 1:1 finite-element model. Both distribution diagrams and numerical field data have been analyzed. With this method, optimal conditions EMU compartment could be feasibly obtained, while optimization evaluation also more efficient. The project cycle shortened, cost reduced dramatically at same time.
