In the present work, the stability of a viscoelastic fluid flow is studied by linear stability theory,
and some results are verified by direct numerical simulation. The investigation considers the …

O presente trabalho investiga a transição laminar-turbulenta devido a ondas de Tollmien-
Schlichting para o escoamento de Poiseuille incompressível, bidimensional, de um fluido …

O estudo do escoamento de jato é relevante devido à sua importância em aplicações
industriais, tais como, sistemas de propulsão, troca de calor e massa e estabilização de …

The purpose of the research is to examine the linear stability of Herschel-Bulkley fluid, a non-
Newtonian fluid, in parallel channel flow. The governing modified Orr-Sommerfeld equation …

Several flows of practical interest are viscoelastic fluids. Due to the industrial applicability of
this type of flow, it is desirable to know how this flow propagates if disturbances appear in …

This paper describes about the effects of yield stress on the linear stability of Herschel-
Bulkley fluid, a non-Newtonian fluid, in parallel channel flow. The modified Orr-Sommerfeld …

Diversos escoamentos de interesse prático são de fluidos viscoelásticos e muitas vezes é
desejável saber se estes escoamentos propagam-se no estado laminar ou no turbulento …

The hexagonal patterns seen in salt lakes around the world are a beautiful phenomena
which goes largely unexplained, despite the importance of such structures in climate …
