metadata.value: It is known that during the filtration flow, if the displacing liquid can chemically react
  with the skeleton while emitting a gas phase, then this flow mode may be unstable. During
  the filtration process, pressure fluctuations will be observed, and the displacing fluid will
  move in waves called “acid waves”. Our research suggests a simple theoretical model that
  gives a qualitative explanation of the causes of this phenomenon. We conducted laboratory
  simulations and detected the boundary of the appearance of “acid waves”, depending on the
  concentration of the chemically active component. At the same time the theoretical model
  can also predict the appearance of “acid waves” in the laboratory experiment, which will
  allow scaling the studied phenomenon in the future.
