Constant Volume Combustion Chamber

A constant volume combustion chamber (CVCC) was constructed to enable material synthesis procedures that are sensitive to temperature, pressure, and ambient species concentrations. Material synthesis processes require specific operating conditions in order to carry out the desired chemical reactions and property transformations, including the creation of paper-templated metals and nanoparticles. The 1.13 liter combustion chamber includes a test stand for conducting the material synthesis experiments. A premixed fuel-air mixture is ignited at a desired equivalence ratio in order to produce the required synthesis conditions. In comparison to furnaces and ovens, this approach provides greater flexibility for materials synthesis procedures. Computational modeling using adaptive mesh refinement, alongside preliminary experimental testing results, confirms that the CVCC can provide the appropriate conditions to synthesize paper-templated metals. The approach demonstrates that the CVCC can be a viable alternative to a furnace for use in materials synthesis applications.
