CFD Analysis of An RC Aircraft Wing 65 III. RESULT AND DISCUSSION 6 The simulation results for initial model (Prototype-I) and e and the modified wing (Prototype-II) were compared. The discussions were focused on the aerodynamics characteristics which include drag coefficient ‘C D’, lift coefficient ‘C L’, and lift-to-drag.

Abstract: This paper describes the aerodynamic configuration design of high subsonic wing using Computational Fluid Dynamic (CFD). The computation was performed using RAMPANT, an unstructured, multigrid flow solver. A geometric model of the wing was created using CATIA (2D and 3D modeling). A corresponding grid was created using preBFC and Author: Nukman Yusoff. Table 1 shows the change of sparse grid collocation points (N sg) from 2 to 10 dimensions with the 2-order accuracy Gaussian quadrature (N tp).In a low-dimensional problem, with the same level p, the sparse grid approach needs more collocation points than the full grid n increases (e.g. n ≥ 5), the number of collocation points of the sparse grid method is much Cited by: 8.
