dc.description.abstractLiquid crystal thermography is a technique for measuring surface temperature and hence, heat transfer coefficient, In . this technique, by measuring the elapsed time to increase the surface temperature of the TLC-coated test specimen from a known initial temperature predetermined value, it is possible to calculate the heat transfer coefficient by solving one-dimensional solution of Fourier's equation. This heat transfer coefficient calculation procedure generally takes inlet temperature as the free stream temperature rather than the local bulk mean temperature, which causes certain errors in the calculated value of h and produces certain difficulty in the design of heat exchangers. So, in this study, several approaches have been discussed and applied for the calculation of h on the basis of bulk mean temperature and the best suitable method has been suggested. Another source of error is the lateral conduction effect, because 1D solution does not take into account the lateral and lateral-longitudinal heat conduction for the determination of heat transfer coefficient. So, in the present study, an approximate 2-D analysis has been provided to calculate the lateral conduction error, which has been also extended for 3-D conduction case. Data reduction has been done by analyzing both the aspects together and finally an improved data reduction method for transient liquid crystal thermography has been developed, that is by consideration of heat transfer in lateral direction and lateral-longitudinal direction (2-D and 3-D heat conduction), as well as on the basis of bulk mean temperature.en_US
