Comparison of two Specified Jets A380-800 & B747-81

Tianguang LU

Abstract

The fluid dynamics analysis was not widely employed. Because fluid dynamics is difficult ̶ the equations governing fluid flows are non ̶ linear, and can only be solved analytically in a few cases.While thesecases proved tobeusefulapproximations of therealsolution inmany situations, the fact was that only through scale model testing in wind tunnels, towing tanks, or other experiments could more precise and detailed information be obtained. Given that the number of venues available for such testing were limited and that the test were not inexpensive, many projectsthatmight havebenefited werenot subjectedtofluid dynamicanalysis. All this has changed in the past few decades with the exponential growth of computer power and the application of Computational Fluid Dynamics (CFD). The object of CFD is to use computers tosolve the previously intractableconservation equations forfluids inorder toaccuratelysimulate. Thus, computational fluid dynamics allows theanalysis of fluid flow problems in detail, faster and earlier in the design cycle than possible with experiments, costing less money and lowering the risks involved inthedesignprocess. This project was going to be a study of the aerodynamic performance and stability competition between A380-800 and B747-8I, since the B747-8I was made as a competitor of A380-800 by Boeing company. When the model for each aircraft was created in this project, many geometre data were missing, so the model for each plane can not be made very accurately. When I use the modelsfordoing theanalysis, manyproblems werecomingout. Anyhow, the results in the project are not accurately, and most problems were from the model for both aircrafts.
