A method for evaluating the thermophysical properties of metal alloys

The simulation of the solidification of metal alloys, a key step in certain industrial processes, requires reliable data on their thermophysical properties such as surface tension and viscosity. Researchers to propose comparing predictive models with experimental results as a method of evaluating these data.

Scientists use surface tension and viscosity data from titanium-based alloys in industrial processes such as casting and crystal growth. Non-equilibrium solidification, modeling for engineering the microstructure of industrial alloysan investigation by ESA (European Space Agency), examined the microstructure and growth of these alloys using the station’s electromagnetic levitator. This facility eliminates the need for containers, which can interfere with experiment results.

Overview of thermal diffusion measurement techniques

Researchers here techniques for measuring the thermal diffusion of molecules in a mixture. Thermal diffusion is measured using the Soret coefficient – ​​the ratio of movement caused by temperature differences to overall movement within the system. This has applications in mineralogy and geophysics, such as predicting the location of natural resources beneath the Earth’s surface.

A series of ESA investigations have studied diffusion, or how heat and particles move in liquids, in microgravity. Selectable optical diagnostic instrument – Influence of vibrations on the diffusion of liquids examined how vibrations affect diffusion in two-component mixtures and SODI-DCMIX more complex diffusion measured in mixtures of three or more components. Understanding and predicting the effects of thermal diffusion has applications in various industries such as modeling underground oil reservoirs.

Research validates ferrofluid technology

Researchers valid the concept of using ferrofluid technology to operate a thermal control switch in a spacecraft. This result could support the development of more reliable and durable spacecraft thermal management systems, thereby increasing mission lifespan and improving crew safety.

Überflieger 2: Research on ferrofluid applications goes orbital analyzed the performance of ferrofluids, a technology that manipulates components such as rotors and switches using magnetized liquids and a magnetic field rather than mechanical systems, which are subject to wear. This technology could reduce the cost of materials for thermal management systems, reduce maintenance and repair needs, and help avoid equipment breakdowns. The paper discusses possible improvements to the thermal switch, including optimizing geometry to better manage heat flow.
