To study the correlation between the resistance pressure drop of the consolidated porous medium and the resistance coefficient,taking the copper mesh with the structural characteristics of the consolidated porous medium as the porous media area,the flow resistance model in the horizontal pipe section was established,and the dimensionless π theorem analysis method was used to derive that the viscous resistance coefficient and the inertial resistance coefficient were related to the Reynolds number and Euler number.The solution methods based on formula method and the fitting method to calculate the porous media resistance coefficient were compared.An experimental device for measuring the resistance coefficient of porous media materials with different structural characteristics was designed.The fluid resistance pressure drop characteristics were studied through experimental measurement and porous transition simulation methods.The results show that:the resistance pressure drop of the copper mesh increases with the increase of the inlet speed;when the inlet speed is small,the resistance pressure drop changes less;with the gradual increase of the inlet speed,the resistance pressure drop changes gradually;under the same speed conditions,the resistance pressure drop of the copper mesh increases with the increase of the mesh;the experimental value of fluid resistance pressure drop in the copper mesh is in good agreement with the simulated value obtained by using the porous jump model.The reliability verification of the porous jump model has practical application value for perfecting the simulation method of studying the porous medium region,and has reference significance for the detailed description of the resistance characteristics of the porous medium.
