撒克逊碗下沉时间的研究

Research on the sinking time of Saxon bowl

研究了撒克逊碗在液体中的下沉时间.通过建立物理模型,结合流体力学过程,分析了碗的质量、液体密度、缺口面积对撒克逊碗在液体中的下沉时间的影响.理论分析结果表明:碗质量或者碗缺口面积的增大,都会导致撒克逊碗下沉时间缩短,而液体密度对下沉时间的影响较小.分别制作了2种类型的撒克逊碗,对理论分析结果进行了验证,实验结果与理论分析基本一致.

The sinking time of Saxon bowl in liquid was investigated both theoretically and experimentally.In theory,through the establishment of the physical model,combined with the hydrodynamics process,the influence of bowl mass,liquid density and gap area on the sinking time of Saxon bowl in liquid was analyzed.The theoretical analysis results showed that,with the increase of the bowl mass or the increase of the bowl gap area,the sinking time of Saxon bowl would be shortened,while the liquid density had little effect on the sinking time.In the experiment,two types of Saxon bowls were made to verify the theoretical analysis results.The experimental results were basically consistent with the theoretical ones,which further proved the correctness of the theoretical analysis.
