HELLO,
I AM FINISHING THE RACE OF INDUSTRIAL ENGINEERING, AND AS FINAL PROJECT DE CARRERA I HAVE THE STUDY IN A WIND TUNNEL.
WHEN DOING THE NUMERICAL SIMULATION OF THE COMPORTAMINTO OF THE FLOW AROUND A CYLINDER, FIRST I MAKE THE MESH IN GAMBIT SOON AND WORK WITH FLUENT, BUT THIS DOES NOT WORK. FOR a CERTAIN VALUE DE REYNOLDS ALL GOOD PQ the CD ADJUSTS ME TO the STANDARD FIRING DATAS, BUT WHEN I RAISE to the Nº OF “RE” the CD GIVES a VERY HIGH VALUE, AND VICE VERSA WHEN UNDER the RE. I HAVE PROVEN INFINITY OF MESHES AND NO IT WORKS TO ME. SOLUTION Q GAVE TO ERA FOR “RE " =1000 ME TO CREATE AROUND THE BODY A LAMINAR ZONE AND THE TURBULENT REST BUT THIS DOES NOT WORK EITHER, AND NOT ALREADY BY WHERE THE PROBLEM CAN COME. PLEASE, IF SOMEBODY KNOWS TO Q ME CAN BE PASSING Q ANSWERS TO ME AS RAPIDLY AS POSSIBLE, THERE IS NOT ONE THAT SOLVES THE PROBLEM TO ME.
