Optimal Sensor Spacing in Experimental Determination of Heat Transfer Coefficient by Inverse Analysis

F. Balkan

Sažetak

It is shown that there exists an optimal spacing of thermo-sensors in the determination of the experimental heat transfer coefficient of a fluid flowing over a plate. The problem is considered as an inverse heat transfer problem with long thin fin model. The heat transfer coefficient of the fluid is estimated from simulated steady-state temperature measurements along the plate. It is shown theoretically that the inner product of the sensitivity vector, JTJ, should be maximum and the group m n d should be equal to 1.692 to obtain the most accurate coefficients, where m is a system parameter containing heat transfer coefficient h, n is the number of thermo-sensors
