![]() | Spacelab - Ferrofluid Thermal conductivity in Microgravity According to my research, this experiment has not been done before on ISS. FerroFluids - Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water). It becomes strongly magnetized in the presence of a magnetic field. In microgravity... natural convection, bouancy forces, sedimentation are absent. To be precise, even basic principles such as 'fluid flow' are greatly altered in Microgravity. So, due to applied magnetic field "Thermomagnetic convection" is also altered to a small extent in microgravity. Hence, Thermal conductivity (Rate of heat flow) in a FerroFluid... will be different in microgravity. Applications- Study of this experiment has applications in developing advanced cooling systems, heat transfer systems, Ferrofluid deformable mirrors and other lot of applications in Aerospace industry. NOTE :- The magnetic field used for the experiment is of small magnitude... hence it doesn't interfere with operation of other instruments onboard the ISS. By plotting the graph of Temperature versus Time for the obtained experimental data thermal conductivity of ferrofluids can be calculated. The data can be fed to the computer onboard the ISS which can calculate the thermal conductivity. Thank you for sparing your precious time and watching the video.

![]() | Thermal Properties of Metal Thermal Properties of MetalOne of the main properties of metal is its ability to conduct and transfer heat. Heat transfer is a physical process of conveying heat energy from a hotter body to a cooler one. Heat can be conveyed directly or through a barrier made of some material. If transmitted spontaneously, heat is always conveyed from a hotter body to a cooler one. The process of heat transfer can't be stopped. We can only slow it down.In real life we often have to deal with this property of metal. There can be many examples: a hot electric stove, where heat is transferred through the walls of aluminium and steel pans to boiling food; hot, but more often barely warm steam radiators; electric heaters with double metal heat accumulators, these help the cold radiators in winter; electric soldering irons whose bits indiscriminately melt lead and tin using all of their power; and of course the great variety of metal heat sinks in radio electronics, these are used to remove heat from microcircuits and transistors, they work day and night at excess voltages to save the latter from overheating.We can add some useful information to the last thing mentioned.Working capacity of various output microcircuits and transistors in radio electronics depends on how quickly heat is removed from their bodies, as well as from their substrates and pads. The material of a heat sink depends on the durability and overall lifetime of a microcircuit or a transistor.Copper heat sinks are especially ... 2010年11月30日再生回数 1068 |
