| Description/Abstract: | The progress of our chemical modeling program is described. This year`s improvements include the development of an enthalpy model for geothermal brines and their coexisting vapor phases. This model may be used to estimate working energy content, liquid/steam ratios, etc. In addition we have developed methods of simulation of geothermal fluids from first principles that promise to supplement experimental data. Examples of the remarkable agreement between theory and experiment for ternary systems are presented here. Significant improvements in our ability to visualize the output of our application software were initiated. These programs will allow the geothermal engineer to rapidly interpret the composition and phase information from model calculations. We also have continued the development of more user friendly interfaces for our geothermal application software. Improvements include an improved method of saving prior calculations and improvements in user options. |
