ABSTRACT. A NUMERICAL MODEL BASED ON THE CHEBYSHEV PSEUDOSPECTRAL METHOD IS PROPOSED FOR SOLVING THREE PROBLEMS WITH DIRICHLET TYPE BOUNDARY CONDITIONS: THE FIRST RELATED WITH THE FLOW DEVELOPED BETWEEN TWO RIGID PLATES WITH ONE FIXED AND THE OTHER WITH CONSTANT VELOCITY; IN THE SECOND THE MOVING PLATE OSCILLATES; AND THE THIRD RELATED WITH THE SHOCK WAVE PROPAGATION GOVERNED BY BURGERS EQUATION. NUMERICAL RESULTS INDICATE THAT THE PSEUDOSPECTRAL METHOD IS CAPABLE OF SIMULATING THE PROBLEMS STUDIED WITH HIGH ACCURACY.
KEY WORDS: CHEBYSHEV PSEUDOSPECTRAL METHOD, BURGERS EQUATION. |
