摘要: The identification of the ratio convective heat transfer coefficient and thermal conductivity two-dimensional polygonal fins on square hexagonal (equilateral-triangular) pitches equivalent radial rectangular fin from a single additional boundary or internal temperature measurement is investigated. This problem motivated by facilities available at University Manchester, which moment make possible only measurement, approached combining element method (BEM) with constrained nonlinear minimization technique. accuracy, convergence, stability proposed numerical respect to level noise added into are carefully analyzed. inaccuracy in results obtained using combined BEM–constrained technique around three nine times less than extra measurements located domain ...
