Week 3 Challenge : CFD meshing on Turbocharger

AIM:

            FOR THE GIVEN MODEL, CHECK FOR THE GEOMETRICAL ERRORS TO MAKE APPROPRIATE VOLUMES. CREATE AND ASSIGN PIDS AS SHOWN IN THE VIDEO. PERFORM SURFACE MESH WITH THE GIVEN TARGET LENGTHS AS PER PIDS.

• BLADE STAGE-1 = 1 mm
• BLADE STAGE-2 = 1mm
• IMPELLER = 2mm
• SHAFT ROTOR = 1 mm
• TURBO CASING = 5 mm
• COMPRESSOR CASING = 5 mm
• INLET CASING COVER = 5mm

PERFORM VOLUMETRIC MESH FOR THE REQUIRED VOLUMES

PROCEDURE:

• INITIALLY OPEN THE GIVE THE TUBRO CHARGER IN ANSA SOFTWARE.
  
• TO CLEAR THE GEOMETRY AND INTERSECTION ERRORS.
  
• USING THE PID SELECTION THE GLITCH HAVE BEEN DELECTED.
  
• NEXT, THE MISSING SURFACES ARE CREATED USING THE NEW TOOL IN FACE OPTION 
  
  
• THE EXTUDED THE SURFACE HAVE BEEN DELETED, NOW THE CREATE THE SURFACE IN THAT COONS PLEASENT THERE.
     
  
• THEN IN TURBINE CASING THE SURFACE IS MISSING.
• USING THE INSERT TOOL THE HOTPOINT IS INSERTED IN THE MIDDEL OF THE ARC
   
• THEN USING THE TRANFORM TOOL IN THE TOP BAR 
    
  
• SELECT THE ENTITIES TO BE TRANSFORMED TO THAT CREATED
• SELECT THE SYMMETRY AND MIRROR 3 POINTS PLANE AND MIDDEL CLICK 
• THEN SURFACE WILL BE TRANSFORMED TO DESIRED PLACE
  
  
  
• USING FILL HOLE OPTION THE HOLE HAVE BEEN CLOSED.
  
  
• THEN USING THE TRANFORM TOOL IN THE TOP BAR, THE COONS CAN PROJECTED.
  
  
• SELCET THE COONS
  
  
• THEN SELECT THE HOTPOINTS ABOVE THE DIRECTION OF THE ARROW MARK.
  
  
  
• NOW THE SURFACE HAVE BEEN CREATED.
• THEN USING THE INTERSECT TOOL IN FACE THE TWO SURFACE ARE CLEARED.
  
  
  
  
• NOW THE INTERSECTION ERROR HAVE CLEARED IN THAT AREA.
  
• NOW IN BLADES AND THE ROTOR SHAFT GEOMETRY ERROR AND INTERSECTION ARE SHOULD BE CLEARED 
  
  
  
  
  
• NOW ALL THE INTERSECTION AND GEOMETRY ERROR ARE BEEN CLEARED.
• THEN ALL THE OPENING SHOULD BE CLOSED BECAUSE IN THE VOLUME MESH THERE SHOULD ANY OPENING THE MODEL.
  
  
• NOW THERE ONLY THE TRIPLE COONS ERROR THESE ERROR CAN'T BE DELETED BECAUSE IT IS ESSENTIAL
  
• NOW THE PIDS SHOULD RENAME IN THE CORESPONDING THE PARTS FOR MESHING EACH PART WITH DIFFERENT MESHING LENGHT AS PER GIVEN LENGTH.
  
  
• NOW THE TUBRO CASING , INLET CASING COVER ,COMPERESSOR CASING , INLETAND OUTLET AND SELCTED AND THE MESHING LENGTH 5mm FOR THAT MINI AND MAXI RANGE IS 3mm AND 7mm
  
  
• THEN USING THE LENGTH IN PERIMETER THE PERIMETERS AND MACORS HAVE BEEN GIVEN 
  
  
• THEN SAME FOR ALL THE BUT MESH LENGTH ALONE CHANGES
  
• FOR BLADES AND SHAFTS ARE 1mm MESH LENGTH
  
• FOR IMPELLER MESHING LENGTH IS 2mm
  
• THEN USING THE VOLUME MESH OPTION, IN THAT THE DEFINE MODLE THE UNNESSCARY PART ARE DELETED
  
  
  
• THEN USING THE TETRA CFD MESH THE VOLUME MESH DONE SEPARTELY ONE BY ONE 
  
  
  
  
  
  
• FINALLY THE VOLUMES MESH IS DONE ENTIRE MODEL.

RESULT: 

           THE GIVEN TURBO CHARGER IS CHECK THE GEOMETRY ERRORS AND INTERSECTION ERROR ARE CLEARED AND AS  PER GIVEN MESH LENGTH THE SURFACE MESH HAS BEEN MESHED FOR EACH PARTS AND VOLUME MESH ALSO DONE. 

LEARNT OUTCOME: 
    FROM THIS CHALLENGE NEW TOOL HAS BEEN LEARNT 

• TRANSFORMS TOOL 
• TRANSFORM TOOL IN FACE 
• VOLUME MESH TOOL
• DEFINE TOOL 
• TETRA CFD MESH
