The living standard of Chinese residents greatly improved during China's current economic development. However, residential building energy consumption has also grown quickly. Therefore, it is critical to carry out building energy conservation in residential premises to ensure both building comfort and controlled energy consumption. Digital technology, an effective tool, could help designers co...

Energy conservation of expressway construction project is urgent in our country, its theoretical research and practice is pretty weak, lack in integrity and corrects conservative evaluation-index system and method. This paper has introduced the theory of vague comprehensive evaluation and the theory of attribute, established a vague comprehensive evaluation model for the energy conservation of ...

An adaptive conservative or dissipative numerical method for nonlinear partial differential equations is established. The method not only inherits the welcome conservation or dissipation property of the equation but also uses suitable non-uniform grids at each time step. Our numerical experiments indicate that the method is useful especially for localized solutions such as solitary wave solutio...

In this paper, we develop a novel energy-preserving wavelet collocation method for solving general multi-symplectic formulations of Hamiltonian PDEs. Based on the autocorrelation functions of Daubechies compactly supported scaling functions, the wavelet collocation method is conducted for spatial discretization. The obtained semi-discrete system is shown to be a finite-dimensional Hamiltonian s...

A numerical finite difference study has been earned out for two dimensional radiation-natural convection interaction phenomena in a vertical circular pin located at a non-participating (i.e. transparent) fluid. The coupled conservation equations in boundary layer (continuity, momentum, and energy equations) and pin energy equation are solved simultaneously using modified box method and fully im...

Lack of energy conservation in lattice Boltzmann models leads to unrealistically high values of the bulk viscosity. For this reason, the lattice Boltzmann method remains a computational tool rather than a model of a fluid. A novel lattice Boltzmann model with energy conservation is derived from Boltzmann's kinetic theory. Simulations demonstrate that the new lattice Boltzmann model is the valid...
