The time-space finite element method was used to study one-dimensional heat conduction problems. Optimum mesh length and time increment of this method were obtained by minimizing the condition number of the coefficient matrix, and were found to be two and three times greater , respectively, than those of the widely used Crank-Nicholson method. Several numerical analyses showed the time-space finite element method to be very stable and precise in comparison with the Crank-Nicholson method. As an application to engineering problems, the one-dimensional time-space finite element method was used for the simplified heat conduction analysis of a turbine blade. A transient analysis on trip condition was performed. This simplified approach was shown to be very effective.
