Training Heat Exchangers — ε-NTU Method

Heat Exchangers — ε-NTU Method

Thermodynamics
Intermediate 120 minutes 5 lessons
Analyze heat exchangers using the effectiveness-NTU method, which avoids iteration when outlet temperatures are unknown. Covers all major configurations with worked problems.

Learning Objectives

  • Define effectiveness ε, NTU, and capacity ratio Cr
  • Apply ε-NTU relations for parallel-flow, counter-flow, and shell-and-tube
  • Handle special cases: condensers, evaporators (Cr = 0)
  • Size and rate heat exchangers without iteration
  • Choose between LMTD and ε-NTU methods for a given problem
