method is estimated in terms of the error norms L₂, L_{∞}, number of nodes in the domain of influence, time step size, parameter dependent and parameter independent RBFs, the numerical validation for the above mentioned three types of PDEs is given to check performance of the new ...
The purpose of the present study is to simulate concentrations of ozone and its precursors (NO and NO 2 ) in an area under the influence of the Candiota coal-fired power station by applying numerical models. The photochemical simulations were conducted during two distinct periods: in summer (fr...
numerical manifold method - continuous deformation - discontinuous deformation analysis - Sichuan-Yunnan area - strain-stress fieldThe numerical manifold method (NMM) can calculate the movements and deformations of structures or materials. Both the finite element method (FEM) for ...
Collected data was also used for validating numerical model of the oxy-fuel combustion model. Stability of the model and its sensitivity on changes of composition of the oxidizer were studied. This simulations were evaluated to check the response of the numerical model on changing the combustion co...
Practically, the convergence could be described as “the property of a numerical method to produce a solution, which approaches the exact solution as the grid spacing, control volume size or element size is reduced to zero” [68]. All discrete conservation equations need to be obeyed in all ...
There is a limit, computed by considering the correct sampling of the impulse response of the free space, which dictates the boundary of application of each method. In this work, the limits of application for these two numerical methods to compute the propagation of optical fields are evaluated...
of verifying the results obtained from the basis of the numerical simulations, experimental testing was conducted. As a verification parameter, the percentage rate of grinding wheel clogging was used. The measurement of clogging was conducted by the optical method taking microscopic images of the ...
摘要: The numerical simulation of the large scale industrial circulating fluidized bed (CFB) boilers, working under air- and oxy-fuel combustion are presented in this paper. Moreover, two-dimensional...关键词: Combustion Chamber Discrete Element Method Solid Volume Fraction Computational Fluid Dynamic...
The numerical methods are devised in a manner such that Richardson extrapolation can be applied to significantly increase the accuracy of the angular fluxes. An analysis of the method is presented for slab geometry transport.DOI: 10.13182/NSE88-A23553 年份: 1988 ...
In order to validate the proposed numerical method, we carried out the 2-D numerical examples shown in Table 2. The accuracy of the method is verified by calculating the maximum relative error δMAX=max{|TANAL.−TNUM.|}/TANAL.MAX and the root mean squared relative error δRMSE=∑i=1...
