Based on the experiments and simulations, it is confirmed that the piezoelectric fan is very effective to cool the plate locally. With the operation of the fan, the temperature at the center of the plate is locally reduced by 28 ☌. Without the fan, the temperature is highest at the center of the plate and lowers toward the plate edge. When a piece of piezoelectric material undergoes physical deformation, an electric charge is generated conversely, when a charge is passed through the. The measured temperature data was used for validation of the numerical results. Piezoelectricity is a characteristic exhibited by certain solids which allows for a linear, reversible relationship between mechanical stress and electrical charge. Such a device is known as a piezoelectric transducer (PZT), which is the prime mover of a piezoelectric fan. There are certain substances, both naturally occurring and man-made, which will produce an electric charge from a change in dimension and vice-versa. 3D unsteady numerical simulations were then conducted to analyze the relationship between the jet flow from the piezoelectric fan and the temperature distribution on the heated plate. Piezoelectric, as derived from Greek root words, means pressure and electricity. The facility consists of a heat source of a thin Ni-Cr foil and a piezoelectric fan for cooling the foil, where the surface temperature on the foil was measured by an IR camera. This will allow you to successfully simulate piezoelectric devices as well as easily extend the simulation by coupling it with any other physics. This is the inverse piezoelectric effect in action, which converts electrical energy into mechanical sound waves. Enable you to debug the models more easily. Sonar works by connecting a voltage to a piezoelectric transmitter. The piezoelectric modeling interface seeks to: Make the modeling workflow more. A test facility was built to investigate the cooling effects of a piezoelectric fan on a heated flat plate in a quiescent atmosphere. The New Piezoelectric Interface, in a Nutshell.
