MIXING OF HOT AND COLD WATER CFD

•  CAD :
  The geometry is a simple 2 inlet pipe with a mixing junction and an outlet. Cold Water enters from one end and combines with hot water coming from the second end at the junction both inlets are velocity inlets and the outlet is pressure outlet set to zero. (NOT A WALL)
  
•  MESHING :
  Learned the importance of slicing up the geometry

Unsliced Geometry

Sliced up geometry

•  Running the solution :
  1) check the mesh
  2) Enable the energy equation and k-epsilon models
  3) set the boundary conditions for the inlet and the outlet and also specify their      temperatures
  4)Intialise the solution and run the calclations
• Results:
  Cold velocity inlet= 0.05m/s hot velocity inlet= 0.05m/s
  Cold water temperature = 300K
  Hot water temperature = 400K
