counter-flow vs parallel-flow
Controls
Presets
Heat exchanger duty Q = U·A·ΔT_lm, where the log-mean temperature difference (LMTD) accounts for how the temperature gap changes along the length. Counter-flow keeps the gap larger, transferring more heat. Educational tool.
Data Inspector
LMTD33.8 K
Heat duty Q16.92 kW
Arrangementcounter-flow
Governing equation
Reading this result: Counter-flow holds the temperature gap open along the whole length, giving an LMTD near 34 K — that is why it out-duties parallel-flow for the same inlet temperatures.
