electrorheological การใช้

• This effect has been used to provide electrorheological Braille displays and very effective clutches.
• Electrorheological fluids change the viscosity of a solution with the application of an electric field.
• Their major goal has been the development of an electrorheological fluid that could be used for clutching in automatic transmissions.
• Unfortunately, the increase in apparent viscosity experienced by most Electrorheological fluids used in shear or flow modes is relatively limited.
• However, an almost complete liquid to solid phase change can be obtained when the electrorheological fluid additionally experiences compressive stress.
• I was unaware that electrorheological fluids exist ( makes sense though ) and that would be a better method of implementation.
• Also, we don't exactly know how long the working life of a device based on electrorheological fluid might be.
• Liquid crystals are under study as electrorheological materials by Dr . Annette D . Shine and her colleagues at the University of Delaware.
• Computer controls could engage or disengage electrorheological transmissions at lightning speed in direct response to electrical signals from the computer, without any expensive mechanical intermediaries.
• The physical and chemical interactions of electrorheological particles with each other and with the liquids in which they are suspended are complex and require fundamental research, she said.
• To surf by touch requires the user to be able to feel depth or hardness; this ability was realized with the first electrorheological tactile mice but never marketed.
• Cornstarch when mixed with a fluid can make a non-Newtonian fluid, e . g . adding water makes Oobleck and adding oil makes an Electrorheological fluid.
• Rheometry is a specific concern for smart fluids such as magnetorheological fluids and electrorheological fluids, as it is the primary method to quantify the useful properties of these materials.
• Daubert, who now teaches at North Carolina State University in Raleigh, agrees that many electrorheological fluids, including melted Hershey bars, lose their special properties when heated too much.
• Cornstarch suspended in kerosene is a typical electrorheological fluid; it has about the consistency of milk, but when an electric field is applied, it becomes as thick as heavy cream.
• The giant electrorheological ( GER ) fluid was discovered in 2003, The major concern is the use of oxalic acid for the preparation of the particles as it is a strong organic acid.
• Winslow retired long ago, but at the age of 93, he still experiments with electrorheology in a basement laboratory at his home in Wheat Ridge, Colo . " There are ways to prevent electrorheological emulsions from breaking down, " he said.
• The PK-3 Plus experiment allows investigating a large variety of topics, for instance : the crystal structure, fluid-solid phase transitions, electrorheological fluids, wave propagation, the heartbeat instability, Mach cone formation and the speed of sound, and lane formation
• When a smart fluid consists of liquid droplets suspended in another liquid ( which is the case with melted chocolate : a suspension of sugar, cocoa powder and milk solids with a little water in liquid cocoa butter ), the droplets may coalesce and separate from the fluid in which they are immersed, destroying its electrorheological properties.
