Transition-zone models for 2-dimensional boundary layers: A review

Transition in incompressible boundary layers with two-dimensional excrescences

An experimental investigation of the transition process in boundary layers subjected to forwardor aft-facing two-dimensional step excrescences is described. The objective of the work was to characterize the variation of transition Reynolds numbers with measurable roughness and boundary layer parameters, with the specific goal of specifying new tolerance criteria for laminar flow airfoils, along...

infinite dimensional garch models

مدلهای گارچ در فضاهای هیلبرت پایان نامه حاضر شامل دو بخش می باشد. در قسمت اول مدلهای اتورگرسیو تعمیم یافته مشروط به ناهمگنی واریانس در فضاهای هیلبرت را معرفی، مفاهیم ریاضی مورد نیاز در تحلیل این مدلها در دامنه زمان را مطرح کرده و آنها را مورد بررسی قرار می دهیم. بر اساس پیشرفتهایی که اخیرا در زمینه تئوری داده های تابعی و آماره های عملگری ایجاد شده است، فرآیندهایی که دارای مقادیر در فضاهای ...

A comparative study of subgrid scale models for the prediction of transition in turbulent boundary layers

DNS of transition in supersonic boundary layers

This paper performs Direct Numerical Simulation of transition induced by blowing and suction in a spatially evolving Mach 2.25 supersonic boundary layer. We use a novel algorithm (Park & Mahesh 2007) capable of solving compressible flow on unstructured grids. Our objective is to evaluate our unstructured capability to simulate supersonic transition. Transition is achieved using controlled perio...
