Abstract:
Provided are a device and a method for testing the compatibility of a gravity-driven two-phase fluid loop. The test device and method can effectively simulate the decomposition process of an ammonia working substance in the gravity-driven two-phase fluid loop in the case of a high temperature with nickel as a catalyst to judge the compatibility of the gravity-driven two-phase fluid loop. Firstly, a test device for simulating the decomposition process of the ammonia working substance in the gravity-driven two-phase fluid loop during a moon day is designed, then the amount of non-condensable gases produced during a moon day from the ammonia working substance in the test device is measured using a method for testing a non-condensable gas in a gravity assisted heat pipe, and then a high-purity nitrogen in the same substance amount as that of the non-condensable gases is filled into the gravity-driven two-phase fluid loop to achieve the determination of the compatibility of the gravity-driven two-phase fluid loop. The test device is simple, and the test method is rapid, convenient and effective.
Abstract:
A thermal analysis step, a molecule ionization step and a molecular structure analysis step are executed in parallel to a temperature increasing step. In the molecule ionization step, component molecules contained in gas evolved from a sample S due to temperature increase are ionized, and in the molecular structure analysis step, any selected ion out of molecular ions obtained in the molecule ionization step is dissociated to generate fragment ions corresponding to the structural factors of the molecule, and the structure of the molecule is analyzed on the basis of the fragment ions.

Abstract:
The invention relates to a method for determining a caloric value, in particular the enthalpy h 2 , the internal energy u 2 , and/or the entropy s 2 , of a gas in a second state. The gas is transferred from a known first state to the second state or from the second state to a known first state in a thermodynamic process, in particular in a compression or expansion process in an engine, in a turbine, or in a compressor. In the method, the caloric value is determined with the aid of at least one analytical function f . The at least one analytical function f depends on the temperature T and on the pressure p or on the temperature T and on the specific volume v and has the following form: f ( T,p ) = g ( T )⋅(1+ k ( p or v, T )). The at least one analytical function f is determined with the aid of materials data for the gas.
