Bu çalışmada pompanın duraklaması ile oluşan kararsız akımları teorik ve deneysel olarak araştırılmıştır
Basınçlar pompa çıkışında ölçülmüştür. Vana ve dirsek kayıpları değişik debiler için ölçülerek yerel kayıp
katsayılarının değerleri doğrudan elde edilmiş ve bu katsayılar için hıza bağlı olarak değişen ampirik bağıntılar
türetilmiştir. Teorik sonuçlar, Karakteristikler Yöntemi kullanılarak ve Fortran dilinde yazılmış bilgisayar
programı ile elde edilmiştir. Sayısal çözümde memba sınır şartını oluşturan pompanın davranışı boyutsuz
parametreler kullanılarak yazılmış yük denge ve hız değişimi denklemleriyle ifade edilmiştir. Deneysel
sonuçların teorik sonuçlarla uyumlu olduğu görülmüş olup gözlenen farklılıkların ihmal edilebilir mertebede
olması kullanılan yöntem ve yaklaşımların uygun olduğunu göstermektedir.
