A high resolution essentially non-oscillatory (ENO) numerical scheme is applied to a new model of heat propagation in crystals for an accurate reconstruction of second sound waves. A splitting of the governing equations allows to approximate the differential terms and the forcing term by means of the ENO scheme and a Runge--Kutta third order scheme, respectively. Results obtained on data relative to a high purity crystal of NaF are in good agreement with the theoretical predictions. 相似文献
