Numerical Simulation of the Freezing Process in Geothermal Boreholes Using Solar Heat Injection

Asymptotic Analysis of Vertical Geothermal Boreholes in the Limit of Slowly Varying Heat Injection Rates

Theoretical models for the thermal response of vertical geothermal boreholes often assume that the characteristic time of variation of the heat injection rate is much larger than the characteristic diffusion time across the borehole. In this case, heat transfer inside the borehole and in its immediate surroundings is quasi-steady in the first approximation, while unsteady effects enter only in ...

consequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir

there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...

Efficient Numerical Simulation of Nonequilibrium Mass and Heat Transfer in Fractured Geothermal Reservoirs

Transient heat andor fluid mass exchange between the permeable fracture system and the surrounding relatively impermeable country rock can be treated in geothermal reservoir simulators using the “MINC” technique. This approach typically requires about an order of magnitude more computer time than the analogous “porous medium” problem. Under practical conditions, the problem can often be lineari...

Numerical simulation of a solar chimney power plant in the southern region of Iran

Three-dimensional numerical simulations are performed to investigate the effects of pressure drop across the turbine and solar radiance on the performance of a solar chimney power plant (SCPP). The SCPP system expected to provide electric power to a city is located in southern region of Iran (city of Lamerd, Fars province). Its dimensions are similar to the Manzanares prototype (built in Spain,...

Evaluation of Eulerian Two-Fluid Numerical Method for the Simulation of Heat Transfer in Fluidized Beds

Accurate modeling of fluidization and heat transfer phenomena in gas-solid fluidized beds is not solely dependent  on the particular selected numerical model and involved algorithms. In fact, choosing the right model for each specific operating condition, the correct implementation of each model, and the right choice of parameters and boundary conditions, determine the accuracy of the results i...
