  • Environmental Heat Capacity of River Received the Tail Water of Surface Water Resource Heat Pump
    Environmental Science & Technology, 2012
    Co-Authors: Li Kai
    Abstract:

    Public hydrodynamic FLUENT software was used to make two dimensional numerical simulation on the Process of tail water discharged into the received water of water resource heat pump of Hongya Hole in Chongqing,the Steady Flow Process in the model by using uncoupled implicit solvers was studied,and the temperature rising area and temperature grads of the influencing source were obtained.As the Flow of thermal discharge was 4 500 m3/h and temperature difference was 6 ℃,it showed that water area was 1 600 m2 if temperature of water rose 1 ℃,which was 2.0% of simulation river acreage area.Boundary value control of temperature rising area with one degree was intercalated,in the condition of mostly polluted,environment heat capacity was 312.5(m3·℃)/s,furthermore the residual environmental heat capacity was 306.25(m3·℃)/s.According to water environment quality standard,capacity of thermal discharge was under the received water,and there was no thermal pollution to ecological environment of the received water.

  • Feasibility Study on Power Generation from Waste Plastics with Partial Precombustion Carbon Capture and Conversion
    Journal of Energy Engineering, 2015
    Co-Authors: John Chase, Chuanwei Zhuo, Yiannis A. Levendis
    Abstract:

    AbstractThe feasibility of upcycling waste plastics into concurrent production of carbon nanotubes (CNTs) and of a hydrogen-enriched gaseous hydrocarbon stream was shown to be possible in a continuous Steady-state Steady-Flow Process. The feedstock was post-consumer (waste) low-density polyethylene (LDPE), which was pyrolyticaly gasified at 800°C, in a Flow of nitrogen carrier gas. The evolving gaseous hydrocarbon pyrolyzates were first used as carbon growth agents for CNTs in a reactor, a Process that lowered their carbon content and increased their hydrogen content. Thereafter, the unreacted hydrocarbon pyrolyzates and the generated hydrogen were mixed with air and burned. This conversion of solid waste plastics to gaseous fuels allowed thorough mixing with air and, upon ignition, the formation of environmentally benign fuel-lean premixed flames for subsequent power generation purposes. The CNT generation in the reactor took place by chemical vapor deposition (CVD) on untreated stainless steel mesh subs...

  • Research on Numerical Parameter Method and Its Application to Tube Inversion Process
    Transactions of Nanjing University of Aeronautics and Astronautics, 1995
    Co-Authors: Nuaa Nanjing
    Abstract:

    A further study of the numerical method to deal with plane-plastic-stress problems with axial symmetry is made on the ground of plastic Flow theory and strain-hardening model of the power function. A set of first-order ordinary differential equations are derived which are suitable for the problems. As an example of application,the equations,together with the so-called Runge-Kutta method,are used to get the numerical solutions of Steady Flow Process in turning the inside-out of a thin circular tube under axial loading.The numerical computation is successful. Stresses and strains are obtained,and the effects of boundary conditions on the Process are analyzed. The theoretical results of inversion loads are compared with the results of experiments. The optimum theoretical result of die radius in which the inversion load is minimum is in good accordance with the experimental one.

  • Lattice Boltzmann simulation of Steady and unSteady Flows through ceramic filter matrix
    Journal of Liaoning Technical University, 2009
    Co-Authors: Ji Zhongli
    Abstract:

    In order to deeply understand the microscopic filtration mechanism of ceramic filter,the Lattice Boltzmann method is used to simulate Steady and unSteady fluid Flows through ceramic filter matrix.The results show that during the Steady Flow Process,the relationship between superficial velocity and pressure agrees well with the Darcy’s law,which confirms the reliability of the LB code.The distribution and change law of microscopic velocity can also be obtained.Velocities at the pore throats are larger,the maximal velocity can be tens times of superficial velocity.Local velocities of points in pores change linearly with the pressure drop,and the local velocities don’t change with calculating steps when the pressure at the entrance is fixed.During unSteady Flow Process,by giving a pressure changing with calculating steps,the change trend of local velocities with pressure is obtained.Results show it indicates that they have a similar change tendency.
