Systems and methods for concurrently exposing a test specimen to a first environment and a second environment

A system for testing materials exposed to extreme conditions, the system comprising:

• a housing defining a chamber;
• a first test specimen received in the chamber, the first test specimen comprising a first outside surface and a first inside surface, the first inside surface defining a first internal volume;
• a second test specimen received in the chamber concurrently with the first test specimen, the second test specimen comprising a second outside surface and a second inside surface, the second inside surface defining a second internal volume;
• a first fluid source fluidly coupled with the chamber of the housing to supply a first fluid to the chamber, the first fluid having a first composition at a first temperature and a first pressure;
• a first pressure control apparatus associated with the first fluid source and configured to control, at least partially, the first pressure of the first fluid;
• a second fluid source fluidly couplable with the first internal volume of the first test specimen to supply a second fluid to the first internal volume of the first test specimen, the second fluid having a second composition at a second temperature and a second pressure;
• a second pressure control apparatus associated with the second fluid source and configured to control, at least partially, the second pressure of the second fluid;
• a third fluid source fluidly couplable with the second internal volume of the second test specimen to supply a second fluid to the second internal volume of the second test specimen, the third fluid having a third composition at a third temperature and a third pressure;
• a third pressure control apparatus associated with the third fluid source and configured to control, at least partially, the third pressure of the third fluid;
• and
• a heat source located in the housing, the heat source defining a heated chamber for receiving the first test specimen and the second test specimen, wherein the heated chamber is configured to control, at least partially, the first temperature of the first fluid, the second temperature of the second fluid, and the third temperature of the third fluid.

A method for testing materials exposed to extreme conditions using a first test specimen and a second test specimen, the first test specimen comprising a first outside surface and a first inside surface, the first inside surface defining a first internal volume, the second test specimen comprising a second outside surface and a second inside surface, the second inside surface defining a second internal volume, the method comprising:

• exposing the first outside surface of the first test specimen to a first environment, the first environment comprising a first temperature, a first pressure and a first composition;
• exposing the first inside surface of the first test specimen to a second environment, the second environment comprising a second temperature, a second pressure and a second composition;
• exposing the second outside surface of the second test specimen to the first environment;
• and
• exposing the second inside surface of the second test specimen to a third environment, the third environment comprising a third temperature, a third pressure and a third composition,
• wherein the exposing the first outside surface, the exposing the first inside surface, the exposing the second outside surface, and the exposing the second inside surface are performed concurrently.
