摘要
建立了高浓度水煤浆长距离管道输运中非稳定段里的数学模型,对模型的求解可以预测非稳定段长度、压力梯度及总的压力损失。模型略作修改后可以计算流量突变后管内阻力损失的变化过程。实验验证了模型的正确性。
A mathematical model of the unsteady flow pipe section has been built up while CWS is transported in a long pipe. By solving the model, length of the unsteady flow pipe section, pressure gradient at every cross-section and the gross energy losses can be predicted. Through a small modification of the model the transition process of the pressure gradient in response to a sudden change of flow quantity may be revealed. Experimental results proved the model's reliability.
