اختيار النموذج المناسب للاضطراب خلال المحاكاة (CFD) أمر ضروري لتمثيل سلوك التدفق الحقيقي و الواقعي والحصول على نتائج دقيقة. في هذا المثال، تمن محاكاة مبدد الطاقة Energy Dissipator باستخدام نموذجين مختلفين لنمذجة الاضطراب. النموذج الأول هو k-omega، والثاني هو النموذج الشائع RNG k-epsilon. وعلى الرغم من أن كلاهما يُستخدم في نماذج RANS لحل معادلات ديناميكا الموائع، إلا أنهما يعتمدان على صيغ شبه تجريبية تتضمن افتراضات وتقديرات تم ضبطها باستخدام نتائج تجارب. أظهر نموذج k-omega سطح ماء متموجًا وحادًّا
