Y Plus Calculation

• Y Plus calculation is important to correct wall heat fluxes for momentum and heat transfer
• CFD engineers should check  Y plus to decide first element adjacent to wall in such a way that, y+ < 1

•   The Y-plus calculation is given, you can enter your values in the column of input values

Calculation of Heat Transfer or Heat Exchanger

• LMTD Method  for the heat exchanger is given on this page
  • Calculate  the average temperature difference (LMTD), ΔTm for a given heat exchanger:
  • Refer to the page for the LMTD calculation
  • Calculate the overall heat transfer coefficient (U)
  • Calculate heat transfer rate: Q= U A ΔTm
