The stepped spillways consist of concrete steps on the spillway discharge channel to assist in the dissipation of the kinetic energy of the water flow. This structure reduces size or eliminates the need for an additional energy dissipator on downstream toe. In this study,  an investigation of nappe flow regime has been carried out to study the influence of operating conditions on the hydrodynamics and mass transfer characteristics on the steps of the spillway by using two-fluid computational multiphase fluid dynamics (CMFD) modeling. The numerical work was performed by means of the program ANSYS CFX 11.0 software. The CMFD results are validated with experimental observation. Thus, the numerical performance of nappe flow  is analyzed.

Basamaklı dolusavaklar, dolusavak yapısından salınan suyun kinetik enerjisini sönümlemeye yardımcı olmak için dolusavak şutu üzerinde yapılandırılan basamaklardan oluşur. Bu yapı, dolusavak boyutu azaltır veya dolusavak sonunda gerek duyulan ek bir enerji kırıcı ihtiyacını ortadan kaldırır. Bu çalışmada, iki akışlı hesaplamalı çok fazlı akışkanlar dinamiği (CMFD) modellemesi kullanılarak, çalışma koşullarının hidrodinamik ve kütle aktarım özellikleri üzerinde akışkan etkisini incelemek amacıyla nap akış rejimi için bir araştırma yapılmıştır. Sayısal çalışma, ANSYS CFX 11.0 bilgisayar paket programı ile gerçekleştirilmiştir. CMFD sonuçları deneysel gözlemle doğrulanmıştır. Sonuç olarak, nap akımının  sayısal performansı analiz edilmiştir.
