Solution Behavior of the Transient Heat Transfer Problem in Thermoelectric Shape Memory Alloy Actuators
The main purpose of this paper is to study the solution behavior of the transient heat transfer problem for one-dimensional symmetric thermoelectric shape memory alloy (SMA) actuators. It is proved that for the transient cooling problem with constant electric current density of magnitude |J | there is a value J0 of |J | such that when |J | < J0, the temperature in SMA is always decreasing to it...
متن کاملON THE ROLE OF THERMOELECTRIC HEAT TRANSFER IN THE DESIGN OF SMA ACTUATORS: THEORETICAL MODELING AND EXPERIMENT By
A combined theoretical/experimental study of the heat transfer in thermoelectric Shape Memory Alloy (SMA) actuators is undertaken in this paper. A one-dimensional model of a thermoelectric unit cell with a SMA junction is developed rst and the transient temperatures in the SMA are evaluated for di erent applied electric current densities. As a rst step towards the design of an actuator, a therm...
متن کاملModeling of Thin Layer Extensional Thermoelectric Sma Actuators
As a rst step towards the design of a high frequency, high force, large strain shape memory alloy(SMA) actuator, we model in this work a thermoelectrically cooled thin SMA layer linear actuator. The SMA is subjected to cyclic phase transition between the martensitic and austenitic phases by alternate heating/cooling, achieved with the thermoelectric Peltier e ect of a pair of P/N semiconductors...
متن کاملEffect of conjugate heat transfer in designing thermoelectric beverage cooler
Peltier technology opens new opportunities for special applications. In the current project, this technology was applied to design and fabricate a portable thermoelectric beverage cooler and thermoelectric cup. The simulation and results of the experiment showed that the common beverage cooler is not a suitable design for ignoring the effect of natural convection in cooling. In our thermoel...
