Title:
|
A STUDY OF AXISYMMETRIC JETS WITH APPLICATION TO THE VLS SYSTEM
|
| |
|
Summary :
|
|
AXISYMMETRIC, TURBULENT, VISCOUS FLOW SIMULATIONS OVER THE FIRST BRAZILIAN SATELLITE LAUNCHER, THE VLS, ARE PRESENTED. THE EMPHASIS OF THE WORK IS ON MULTIBLOCK CALCULATIONS FOR AFTERBODY FLOWS WITH PROPULSIVE JETS. A BRIEF DESCRIPTION OF THE NUMERICAL METHOD, BASED ON THE BEAM AND WARMING IMPLICIT APPROXIMATE FACTORIZATION ALGORITHM, AS WELL AS OF THE MULTIBLOCK IMPLEMENTATION IS PRESENTED. TURBULENCE CLOSURE IS OBTAINED IN THE PRESENT CASE THROUGH THE USE OF THE BALDWIN AND BARTH ONE-EQUATION TURBULENCE MODEL. RESULTS FOR VARIOUS JET PRESSURE RATIOS AND FREESTREAM MACH NUMBER FLOWS ARE DISCUSSED. THE RESULTS OBTAINED DEMONSTRATED AN EXCELLENT QUALITATIVE AGREEMENT AND ALSO A VERY GOOD QUANTITATIVE AGREEMENT WITH THE AVAILABLE DATA. RESULTS FOR FLOW CONDITIONS REPRESENTATIVE OF ACTUAL VLS FLIGHT ARE ALSO PRESENTED AND DISCUSSED.
KEYWORDS: VLS, AXISYMMETRIC JETS, TURBULENT FLOW, MULTIBLOCK GRIDS, FINITE DIFFERENCES.
