Differences between Steam-water and Air-water Capillary Pressures
Steam-water flow exists in most geothermal reservoirs where steam-water capillary pressure plays an important role in controlling fluid distribution, transfer of liquid between fracture and matrix, well productivity, and even the reserves. However, it is very difficult to measure steam-water capillary pressure due to the phase transformation and the significant mass transfer between the two pha...
متن کاملinvestigation of water balance in water recovery of closed steam injection gas turbine cycles
an industrial gas turbine has the characteristic of decreasing output power on hot summer days while electricity demand peaks. steam injection in gas turbines has been used for many years to prevent the loss of performance of gas turbines caused by high ambient temperature. vodoley system is a closed steam injection gas turbine cycle (csigtc), which is known as a self-sufficient in steam produc...
متن کاملAn Experimental Method of Measuring Steam- Water and Air-Water Capillary Pressures
An experimental method was developed to measure both steam-water and air-water capillary pressures using an X-ray CT technique. We conducted spontaneous water imbibition and gravity drainage in ceramic core samples for steam-water and air-water systems respectively. The results were compared, and it was found that the steam-water capillary pressures were significantly less than the airwater cap...
متن کاملDifference between Steam-water and Air-water Relative Permeabilities in Fractures
The goal of this research has been to compare steamand air-water transport through fractured media and gain better understanding of the behaviors of relative permeability in fractures. Airwater (or nitrogen-water) relative permeabilities are often used for geothermal reservoir simulations while steam-water relative permeabilities in fractures are rarely measured owing to difficulties and comple...
متن کاملOn the Mixed-CSP problem
In the classical Constraint Satisfaction Problem(CSP) two finite models are given and we are asked to find their homomorphism. In the Mixed-CSP problem, besides the models, a set of weighted pairs of elements of this two models is given and the task is to find a homomorphism that maximizes the weight of pairs consistent with the homomorphism, i.e. pairs for which homomorphism maps the first ele...
