Viscous Heating in a Fluid Damper
Model ID: 8568
Fluid dampers are used in military devices for shock isolation and in civil structures for suppressing earthquake-induced shaking and wind-induced vibrations, among many other applications. Fluid dampers work by dissipating the mechanical energy into heat. This model shows the phenomenon of viscous heating and consequent temperature increase in a fluid damper. Viscous heating is also important in microflow devices, where a small cross-sectional area and large length of the device can generate significant heating and affect the fluid flow consequently. The Conjugate Heat Transfer, Laminar Flow and Moving Mesh interfaces are used with a time dependent study in this model.
