@李东岳 李老师，您有没有求解器植入MRF或者气泡旋转类的资料,可以推荐下不?

@vortex 是的 我课题组的代码也是您说的这种 是两部映射法里面中间步用f更新了速度再求压力泊松方程方程再更新最终速度 然而改到openfoam发现出了点小问题:136:

在看《Computational Fluid Dynamics of Dispersed Two-Phase Flows at High Phase Fractions》的时候碰到一个不太理解的地方。
一般的相间动量传递可以写成方程（3.10）
1.png
为了模拟phase inversion， 方程（3.11）加入了b相变成离散相时的曳力、升力等。
但对于方程(3.11)的曳力相，如果仍然是a相为离散相的情况，$\alpha_a$→0 ，$ f_a$→0，
那曳力相前面的部分不就变成$3/4\alpha_a\alpha_b(f_b\frac{C_{db}\rho_a}{d_b})$，和（3.10）里的不一样，b相变成分散相时候应该才是这个形式，虚拟质量力也是一样的情况。 升力也对不上。

突然想到这个帖子，通过调整边界层厚度可以达到收敛了。

@李东岳 李老师好，空气密度设为1000的情况流场数据在0.0489范围之内，虽然顶部看起来不好看。
相分数初始场：

#include "../include/initialConditions" defaultFieldValues ( volScalarFieldValue alpha.air 0 volScalarFieldValue alpha.saltwater 1 volScalarFieldValue alpha.water 0 ); regions ( boxToCell { box ($xyz_min 0.1 $xyz_min) ($xyz_max $xyz_max $xyz_max); fieldValues ( volScalarFieldValue alpha.air 1 volScalarFieldValue alpha.saltwater 0 ); } boxToCell { box ($xyz_min 0 $xyz_min) ($xyz_max 0.1 $xyz_max); fieldValues ( volScalarFieldValue alpha.saltwater 0 volScalarFieldValue alpha.water 1 ); } );

速度场

#include "../include/initialConditions" dimensions [0 1 -1 0 0 0 0]; internalField uniform ($velocity 0 0); boundaryField { inlet { type fixedValue; value uniform ($velocity 0 0); } outlet { type inletOutlet; inletValue uniform (0 0 0); value $internalField; } atmosphere { type pressureInletOutletVelocity; value uniform ($velocity 0 0); } bottom { type slip; } front { type symmetryPlane; } back { type symmetryPlane; } }

压力场

dimensions [1 -1 -2 0 0 0 0]; internalField uniform 0; boundaryField { inlet { type fixedFluxPressure; value uniform 0; } outlet { type zeroGradient; } atmosphere { type prghPressure; rho rho; p uniform 0; value uniform 0; // optional initial value } bottom { type fixedFluxPressure; value uniform 0; } front { type symmetryPlane; } back { type symmetryPlane; } }

这个问题卡住好久了，但没有思路调整哪些参数，希望李老师能指点一下

@李东岳 , 李老师您好，我已经在chtMultiRegionFoam中植入了第一张图所示的拉普拉斯及泊松方程，

QQ截图20210619102650.jpg

QQ截图20210619102636.jpg

实现了对电势在流固区域的耦合求解，但电荷的求解似乎不对，然后电场力的求解结果也和参考文章里面差的太多，但我边界设置理论上是符合文章要求的，第二张图和第三张图是我和参考文章计算结果的对比。参考文章及我的算例和编译的求解器链接放在这里：https://pan.baidu.com/s/1U8NBBon8CFVvDoF9Fsi9UA 提取码：mppz
麻烦李老师能抽空看一下，检查一下问题，不胜感激。一个头俩大:136: :136:

@conghongchuan 提高一下热度，我可不可以理解成：把气泡替换成旋转机械，就是旋转速度了。

关于网格尺度小了以后interpolation和mapping的问题

这个算例太酷炫了 小液滴都算出来了 还特别圆

@chengan-wang 在 关于codedFixedValue使用 中说：

我定义了ymax，之后如果我使用if ( Cf[faceI].y() > ymax ) 设置相分数，时间步长越来越小。但如果改成if ( Cf[faceI].y() > 0.1 ) 一个具体数值，情况就好很多。我的使用方法是否有问题呢？

理论上不应该有任何问题 :jingya:

@浪迹天大 这样嘛。。。好的，谢谢！

如题，想用Foam-extend里的浸没边界法（Immersed Boundary Method）求解器，解决水与弹性杆的流固耦合数值模拟，有人有这方面经验吗？

@static 你好，我最近也在做三维飞机的相关数值模拟，可否给个联系方式，请教一些问题。谢谢，这是我的qq：3310792254

@李东岳 很抱歉才看到老师的回复。感谢老师，我已经自己解决啦:xinxin:

图挂了

@李东岳 东岳老师，我在dynamicMeshDict里设置了constrints和restraints两个条目，控制圆柱仅在y方向移动，不转动，如下：

constraints { yLine { sixDoFRigidBodyMotionConstraint line; centreOfRotation (0 0 0.5); direction (0 1 0); } noRotation { sixDoFRigidBodyMotionConstraint orientation; } } restraints { verticalSpring { sixDoFRigidBodyMotionRestraint linearSpring; anchor (0 0 0.5); refAttachmentPt (0 0 0.5); stiffness 2.1055; damping 0; restLength 0; } }

不知道您说的是不是这个意思？

@李东岳 感谢李老师百忙之中指点！这么来看correction(fvm::ddt(p))就代表前后时间步压力差值的时间变化率啦

各位大佬好，想请教一下，我想显示一个密度、体积不断变化的物体的质量，请问大家有什么好办法吗？
