Abstract
The TRUE-2 module was the re-flight of a previous module, TRUE, Thermal Radiation Unsteady Experiment, flown onboard Maser 8 in 1999. Aim of the TRUE module was to detect and measure the forces produced by a temperature gradient crossing the interface between a solid body and a liquid in which it is immersed. These forces are named Thermal Radiation Forces (TRF) introduced and theorized by the Principal Investigator of the scientific team.
The experimental procedure foresaw the activation of two distinct thermal ramps; surprisingly, the second ramps generated a force signal higher than that generated by the first thermal wave front. This aspect has requested a deep analysis by the scientific team. Improved numerical simulations of the thermal field generated inside the cell and of the ensuing fluid motion induced by the residual gravity level have been used as a powerful tool for evaluating a variety of effects related to the application of the temperature gradient.
