Five industries that use thermoacoustics for greater efficiency

by Ecofriend1874

You must have observed the Thermoacoustic effect when partly molten glass tubes connect to different glass vessels. The spontaneously loud and monotone sound is produced. Similar effect is observed in stainless steel tube with one side kept at room temperature and the other is in contact with liquid helium at 4.2. The major role of thermoacoustic can be seen in heat engines. But now, thermoacoustics are used in air-conditioners, refrigerators and cryogenic applications.

Here are some devices that use sound waves to harness energy with the help of thermoacoustics. Let’s check out how thermoacoustics is being used nowadays.

  • One recently started company invented a new type of engine that could generate electricity with the help of a fuel cell, but the only problem is the cost of the internal combustion engine. The designed engine is in the form of a basketball, which helps in electricity production for the generation of power and heat in homes, which is also a way to harness the heat produced by the solar collectors. The company has created only a prototype but working on increasing efficiency. So it started using the thermoacoustic technology to increase its efficiency where the heat is controlled by the intensity of sound waves. Therefore, if you can produce more frequency sound waves, you can harness more energy. By doing this, the company already got 10 percent increase in the efficiency and still working on more.

  • The efficiency of Stirling Engine is also increased with the help of thermoacoustics. Stirling engine principle relies on the cycle of expansion and contraction that turns the heat into mechanical work by moving the piston. But the only problem is the high temperature and pressure, so it may use the sound wave controlled technology to eliminate all rubbing parts and seals which are prone to wear and tear.
  • The recently developed Score-Stove also harnesses waste heat to power a thermo acoustic engine to provide energy to areas where electricity is limited. In the Score-Stove, there is no moving parts. The Score-Stove is eco friendly, which reduces gas emissions as well.

  • Thermoacoustic technology is also being used in Cool Sound Industries, Inc. for an air conditioning system that uses no HFC, no HCFC or any other mechanical compressors.
  • Thermoacoustic commercial application can be witnessed mainly in medium cryogenic industries.
