文摘
- •
Axial conduction effects in laminar counterflow parallel plate heat exchangers are studied analytically.
- •
The exact solution is written in terms of eigenfunction series expansions.
- •
An analytical eigencondition is obtained which provides the eigenvalues numerically.
- •
The exact solution is validated against finite-difference solutions and results from other authors.
- •
The semi-analytical solution enables future spectral and parametric studies of the problem.
