Despite numerous observational and theoretical attempts, the heating problem of the solar chromosphere still remains unsolved. We develop a novel 3D two-fluid model that accounts for dynamics of charged species and neutrals, and use it to perform the numerical simulations of granulation driven jets and associated waves in a quiet region of the solar chromosphere. The energy carried by the waves is dissipated through ion–neutral collisions, which are sufficient to balance radiative energy losses and to sustain the quasi-stationary atmosphere whose ion and neutral number densities, ionization fraction, and temperature profiles are relatively close to the observationally based semi-empirical model. Additional verification of our results is provided by a good fit of the numerically predicted waveperiod variations with height to the recent observational data. These observational validations of the numerical results demonstrate that the wave heating problem of a quiet region of the ch...

太阳安静层大气波加热的3D数值模拟

尽管进行了大量的观察和理论尝试，但太阳色球的加热问题仍然没有解决。我们开发了一种新颖的3D两流体模型，该模型解决了带电物质和中性粒子的动力学问题，并使用它在太阳色球层的安静区域中执行了由造粒驱动的射流和相关波的数值模拟。波所携带的能量通过离子-中性碰撞而消散，这足以平衡辐射能损失并维持准静态大气，其离子和中性数密度，电离分数和温度曲线相对接近于观测值半经验模型。数值预测的波高随高度变化与最近的观测数据的良好拟合，为我们的结果提供了进一步的验证。这些对数值结果的观测验证表明，在一个安静的区域中，波的加热问题...
