A new flow mixing calorimeter for operation on gases at high temperatures and pressures

A new flow mixing calorimeter for operation at temperatures up to 700 K and pressures up to 30 MPa is described. The calorimeter is designed for use with dense gases of supercritical fluids. The design features a reverse flow labyrinth containing stainless steel gauze discs to promote turbulence and ensure efficient mixing. The reverse flow design confines temperature gradients to the centre of the calorimeter, and ensures that heat leaks are small. Values of the excess molar enthalpy, HmE of argon plus steam obtained using the calorimeter were found to be independent of flow rate over a tenfold range.
