In this study, a small-scaled Tyrolean weir model was constructed in the laboratory environment and a series of experiments were conducted on it, for two different rack inclinations (θ₁ = 18° and θ₂ = 25°) and three different bar spacings (e₁ = 3 mm, e₂ = 6 mm and e₃ = 10 mm) for a range of upstream flow discharges. The flow rates passing through the racks and going downstream over the racks were measured. Empirical equations for the discharge coefficient and water capture capacity of the Tyrolean weirs were determined by applying dimensional analysis to the parameters involved in the phenomenon. The related dimensionless parameters were presented with graphs and empirical equations for discharge coefficients were derived, coefficient of determination R² of equations for θ₁ = 18° and θ₂ = 25° are found 0.838 and 0.825 respectively. According to results obtained from experimental data, C_d increases as the Froude number ((F_r)_e) between bars increases and water capture capacity [(q_w)_i/(q_w)_T] of the racks decreases with increasing ((F_r)_e). Also, a numerical model of the Tyrolean weir was generated by using Flow-3D software and it was shown that the results of the numerical analysis were very consistent with the physical model results at large bar spacing such as e = 10 mm. As the bar spacing (e) reduces, the success of the numerical model giving consistent results with physical model is decreasing.

在本研究中，在实验室环境中构建了一个小型蒂罗尔堰模型，并对其进行了一系列实验，针对两种不同的齿条倾角（θ ₁  = 18° 和θ ₂  = 25°）和三种不同的钢筋间距( e ₁  = 3 毫米, e ₂  = 6 毫米和e ₃ = 10 mm) 用于一系列上游流量排放。测量通过支架并通过支架向下游流动的流速。蒂罗尔堰的流量系数和水捕获能力的经验方程是通过对现象中涉及的参数应用量纲分析来确定的。相关的无量纲参数用图表表示，并推导出了流量系数的经验方程，θ ₁  = 18°和θ ₂  = 25°方程的决定系数R ²分别为0.838和0.825。根据实验数据得到的结果，C _d随着弗劳德数（（F _r) _e ) 条之间的增加和水捕获能力 [ (q _w ) _i /(q _w ) _T ] 随着增加 ( (F _r ) _e ) 减少。此外，使用 Flow-3D 软件生成了蒂罗尔堰的数值模型，结果表明，数值分析结果与e  = 10 mm等大钢筋间距下的物理模型结果非常一致。随着条间距 ( e ) 的减小，给出与物理模型一致结果的数值模型的成功率正在下降。
