Abstract
The thermal effect for wave propagation in a fluid-filled annular elastic steel tube is found to be very important. This effect can cause a 15% difference (the average for water and glycerin) with that neglecting the thermal effect with the system equations. However, for an elastic steel tube or a fluid line alone, the thermal effect is small (< 1 %) under the conditions of room temperature and the radius ratio of inner to outer radii is 0.93. The mechanism for the importance of the thermal effect in the coupled fluid-solid problem is related to the relatively higher thermal conductivity at the solid wall which conducts away heat from the relatively insulated viscous liquid boundary layer.
