资源简介:

The folder contains the simulation results corresponding to the computational fluid dynamics study: Effects of Chiari type 1 malformation on cerebrospinal fluid dynamics during arterial pulsations and coughing Data is organized in the following way with files in .csv and .xlsx format Cropped model: output_*: flow time in seconds, pressure in the fourth ventricle (Pv), outflow in m³/s or kg/s, and pressure at plane in spinal SAS (Psas) for physical herniations and herniations created by porous zones Full model arterial_pulsations: data with all boundary conditions (arterial) except from cough arterial_pulsations_and_cough: data with all boundary conditions (arterial) including cough file content: *_boundary_data: time step number, number of coupling iterations necessary per time step, flow time (s), pressure (P) and flow (Q) at outlets with interstitium (1), spinal (2), lymphatic (3) and arachnoid villi (4), first element of Jacobian (J11), flow residual, value of perturbation (dP) in Pa, converged?: 1 when converged, 0 when not, perturbation parameter, number of times the perturbation value needed to be reduced. *_flow: flow time in seconds, volumetric flow through aqueduct, and spinal SAS *_pressure_data: flow time in seconds, relative pressure compared to interstitium outlet at the fourth ventricle (v4), the spinal SAS (sas) and the lateral ventricle (lv)

本文件夹收录了一项计算流体动力学(computational fluid dynamics)研究的仿真结果,该研究探讨Chiari 1型畸形(Chiari type 1 malformation)在动脉搏动与咳嗽过程中对脑脊液动力学(cerebrospinal fluid dynamics)的影响。 数据采用.csv与.xlsx格式的文件进行组织,具体结构如下: 裁剪模型(Cropped model): output_* 系列文件包含:流动时间(单位:秒)、第四脑室压力(Pv)、流出量(单位:m³/s 或 kg/s),以及脊髓蛛网膜下腔(spinal SAS)平面处的压力,分别对应物理性疝以及由多孔区域构建的疝模型。 完整模型(Full model): 分为两类数据集: - arterial_pulsations:包含除咳嗽边界条件外的所有动脉边界条件相关数据 - arterial_pulsations_and_cough:包含咳嗽在内的所有动脉边界条件相关数据 文件内容说明: - *_boundary_data:各列依次为:时间步编号、每个时间步所需的耦合迭代次数、流动时间(秒)、带间质间隙的出口(1)、脊髓出口(2)、淋巴出口(3)以及蛛网膜绒毛(4)处的压力(P)与流量(Q)、雅可比矩阵(Jacobian)首元素(J11)、流量残差、扰动值(单位:Pa,记为dP)、收敛标志(收敛时为1,未收敛时为0)、扰动参数、扰动值所需的调整次数。 - *_flow:各列依次为:流动时间(秒)、导水管体积流量以及脊髓蛛网膜下腔流量。 - *_pressure_data:各列依次为:流动时间(秒)、相对于间质间隙出口压力的第四脑室相对压力(v4)、脊髓蛛网膜下腔相对压力(sas)以及侧脑室相对压力(lv)。
