Fluent入门验证案例 | 非对称扩展通道的低雷诺数流动仿真

本案例为入门案例，对在轴对称扩散器中对完全发展的湍流进行建模。对气流在入口处完全发展到扩散器进行仿真计算。并对沿发散扩散器壁的压力系数比较进行监测，与文献的计算结果进行比较，实现对仿真计算准确性的验证。适合fluent初学者练手使用。1workbench设置本案例具体设置如下图：workbench设置示意图2FLUENT设置2.1General设置与网格导入首先导入网格，然后勾选为稳态计算，并选择压力基求解器。并选择轴对称选项。通用设置示意图2.2材料设置依据相关文献中的数据，对材料进行设置，密度为1，年粘度为1.64e-5，相关设置如下如所示：流体材料设置示意图2.3模型设置本案例所选用的模型为ke模型，相关设置如下图所示：湍流模型设置示意图2.4边界条件设置首先将prof文件导入，具体的prof文件内容如下图：C((inletpoint1610)(x-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00-6.000000e+00)(y0.000000e+001.673701e-023.346486e-025.017432e-026.685632e-028.350178e-021.001016e-011.166471e-011.331293e-011.495397e-011.658698e-011.821112e-011.982558e-012.142958e-012.302234e-012.460310e-012.617116e-012.772581e-012.926638e-013.079222e-013.230273e-013.379731e-013.527540e-013.673648e-013.818006e-013.960566e-014.101285e-014.240123e-014.377043e-014.512011e-014.644994e-014.775965e-014.904901e-015.031777e-015.156577e-015.279281e-015.399879e-015.518358e-015.634711e-015.748932e-015.861019e-015.970970e-016.078788e-016.184477e-016.288043e-016.389493e-016.488838e-016.586090e-016.681263e-016.774372e-016.865433e-016.954467e-017.041491e-017.126527e-017.209598e-017.290727e-017.369937e-017.447255e-017.522706e-017.596318e-017.668117e-017.738131e-017.806391e-017.872924e-017.937760e-018.000928e-018.062460e-018.122385e-018.180734e-018.237538e-018.292826e-018.346630e-018.398980e-018.449907e-018.499442e-018.547613e-018.594453e-018.639989e-018.684253e-018.727273e-018.769078e-018.809698e-018.849160e-018.887492e-018.924723e-018.960879e-018.995988e-019.030074e-019.063166e-019.095288e-019.126465e-019.156722e-019.186084e-019.214574e-019.242215e-019.269031e-019.295043e-019.320273e-019.344743e-019.368475e-019.391488e-019.413803e-019.435438e-019.456414e-019.476749e-019.496461e-019.515569e-019.534089e-019.552038e-019.569434e-019.586292e-019.602628e-019.618456e-019.633794e-019.648653e-019.663050e-019.676998e-019.690509e-019.703597e-019.716275e-019.728556e-019.740450e-019.751970e-019.763128e-019.773933e-019.784397e-019.794531e-019.804345e-019.813847e-019.823049e-019.831958e-019.840584e-019.848937e-019.857024e-019.864853e-019.872433e-019.879771e-019.886876e-019.893753e-019.900411e-019.906856e-019.913094e-019.919133e-019.924979e-019.930637e-019.936114e-019.941415e-019.946546e-019.951512e-019.956319e-019.960971e-019.965473e-019.969831e-019.974048e-019.978130e-019.982080e-019.985903e-019.989602e-019.993182e-019.996647e-011.000000e+00)(z0.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+000.000000e+0
