Reversing Thermal Equilibration by Differential Magneto-Thermal Force

A special magnetic body force was proposed to reverse thermal equilibration in a fluid [1]. In this work, we discuss the fulfilment of the requirements for this force and the experiment to verify it. We present experimental [2-3] and analytical [4] results that clearly demonstrate: 1) approaching thermal equilibrium in our magnetic fluid sample was indeed “reversed” as the magnetic body force introduces the localized flows that stop the conventional convective heat transfer; 2) The differential magneto-thermal force density calculated with experimental parameters agrees with the design principle. These results prove the feasibility of the proposed mechanism for a new generation of heat transfer apparatus that has high efficiency and no exhaust, a clean energy source that will improve our environmental protection.
