A new device for heating viscous fluids is proposed in which elastic vibrations are applied to the heating element in order to enhance heat transfer. The vibrating force field intensifies heat transfer when the device is operated in resonance mode. A simplified theoretical model is described for determining the relationships among the device parameters governing the resonance mode. The model was validated against experimental data and found to be suitable for engineering design of the system. The efficiency of the device in promoting heating of viscous fluids is demonstrated experimentally for healing glycerin.
