| contents | Spreading Simulation of Droplet Impact on Solid Surface with CLSVOF Method and Its Experimental Verification Yan-Jun Zhang Ping Li Física, Astronomía y Matemáticas Impact Droplet Contactline CLSVOF method A coupled volume-of-fluid and level set (CLSVOF) method is applied for the simulation of droplet impacting on a solid surface. This two-phase flow approach combines the advantages of VOF and level set (LS) methods. Three cases are listed and simulated by CLSVOF method, and the wettability is evaluated by tracking the three-phase contact line (TPCL). Results showed that the change of liquid spreading ratio with time has a good fit with the experimental results of the above three cases and high accuracy is achieved by CLSVOF method compared with VOF method, which indicated that this model is suitable for researching the wetting problem. The spreading speed on good wettability surfaces is faster than that of on poor wettability surfaces significantly, and the recoiling phenomenon appears after the droplet spreading to its maximum. 2016 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46444888013 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2 Vol.46 |
