In order to investigate the condensation heat transfer and pressure drop characteristics in tube-side flow of spiral wound heat exchanger (SWHE), a computational model based on two-fluid multiphase model, k-ε turbulence model and thermal phase change model was established considering the gravity and surface tension.
A full-scale three-dimensional Eulerian-Eulerian numerical model was established considering absorbing reactions in which the two-film theory model was adopted to describe the absorption process of SO2 and NOx.
FE model is established considering the geometrical nonlinearity.
2. In fractured member, a 3D weak plane model is established considering natural fracture׳s (weak plane) orientation and mud invasion.
The mathematical model is established considering that the glioma cells are of two phenotypes: migratory and proliferative.
An optimization model is established considering the shape-related variables and several other envelope-related design variables such as window ratios and overhangs.
A FE model was established considering material non-linearity and shear transfer between steel and concrete and compared with the experiments, which showed good agreement and clarified the load transfer mechanism.
In order to simulate non-Darcy flows in low and ultra-low permeability reservoirs, based on the black oil simulator, a three-dimensional, two-phase model was established considering two-phase start-up pressure, permeability sensibility and fracture conductivity decline.
Based on the theory of product life cycle, the evaluation index system of product maintainability and its calculation model are established considering its inherent attributes and external factors at the same time.
