Space has no gravity in it and therefore the dynamics of motion operate very differently than on Earth. The application of numerical methods in the improvement of safety of aeronautical structures has been demonstrated in this work through examples in which advanced numerical methods have been used in the structural analyses. 0000004809 00000 n. Numerical results show that there exist two inverse elliptical flow fields and temperature fields. Contact us if you experience any difficulty logging in.

Results show that the local contribution to intermittency in polymer flow is relatively small, leading to the suppression of intermittency in forced homogeneous isotropic turbulence with polymer additives. In the article “Direct numerical simulation of noninvasive channel healing in electrical field,” a numerical model is established for the new concept of channel healing via adding small iron particles driven by an external electric field. In the article “The effect of Knudsen diffusion and adsorption on shale transport in nanopores,” a physics-based continuum model, considering gas transport mechanisms in shale reservoirs, is employed to simulate the flow transport in nanopores. This numerical investigation provides valuable reference and tools for further simulation of real pipe healing in engineering. Thus, numerical methods become more and more important and their modern developments are worth exploring. This site uses cookies. What computers can’t do • Solve (by reasoning) general mathematical problems they can only repetitively apply arithmetic primitives to input. Dr Haifeng Shi is also appreciated for his support of this special collection.

In the article “Three-dimensional numerical study on flow dynamics characteristics in supercritical water fluidized bed with consideration of real particle size distribution by computational particle fluid dynamics method,” the computational particle fluid dynamics method is applied to study the detailed flow behaviors inside a supercritical water fluidized bed, considering the limitation of the two-fluid method and discrete element method. 5, No. Part of You are currently using the site but have requested a page in the site. Based on the CFD and tests, the non-uniform seal geometry parameters are presented to improve the uniformity of pressure loads on teeth. Iteration method 4. Simulations of the varying law of the generalized coordinate variables and the trajectories of the SCARA robot are performed to fulfill the aim of dynamic modeling. Would you like to change to the site? In the article “Optimal design of heating system for electrical rapid heat cycle mold based on multi-objective optimization, multiple-attribute decision-making, and conformal design theory,” an optimal design methodology of heating system is proposed to increase the heating efficiency and decrease temperature distribution of electrical rapid heat cycle molding (ERHCM) mold. • Represent all numbers. Numerical Analysis comes handy in making these estimations with the help of linear as well as non-linear equations that are computed by onboard computers. • Solve problems exactly. Access to society journal content varies across our titles. Edited by: Lutz Angermann. This numerical investigation provides valuable reference and tools for further simulation of real pipe healing in engineering. Such problems arise throughout the natural sciences, social sciences, engineering, medicine, and business. For example, parallel computing largely promotes the precision of direct numerical simulations of turbulent flow to capture undiscovered flow structures. 41-43, Applied Mathematical Modelling, Vol. For more information view the SAGE Journals Article Sharing page. Common parameters for fire sites are identified via simulation and regression. The soul of numerical simulation is numerical method, which is driven by the above demands and in return pushes science and technology by the successful applications of advanced numerical methods.
