We are pleased to invite you to the Spring School on Transition and Turbulence (EPTT). The 13th edition will be held in Blumenau, Santa Catarina, from September 19th to 23rd, 2022, organized by the University of Blumenau (FURB).

 

In 2022 the School will keep its well-established tradition to bring together professionals and students to discuss the area of Transition and Turbulence in Fluid Mechanics in the form of lectures on fundamental concerns. It also has the intention of providing opportunities for students, researchers, and professors to expose their recent work to the community in oral and poster sessions.

 

The last edition (2020) was in the online format due to the coronavirus (COVID-19) pandemic. Now, we intend to gather the transition and turbulence scientific community again with the in-person format in the Brazilian Oktoberfest city, Blumenau.

 

Topics of interest:

– Aerospace Engineering: Propulsion

– Aerospace Engineering: Aerodynamics

– Bioengineering

– Fluid Mechanics and Rheology: Computational Fluid Dynamics

– Fluid Mechanics and Rheology: Instrumentation and Experiments

GFRP profiles subjected to fire: from laboratorial test to multiphysics modelling

Prof. Carlos Manuel Tiago Tavares Fernandes, University of Lisbon

Glass Fibre Reinforced Polymers (GFRP) have several advantages over conventional building materials, namely in terms of strength, self-weight, insulation properties and durability. Although the mechanical and physical properties of pultruded GFRP profiles are reasonably studied, their response to fire is still an active topic of research. Even though flame retardants and phenolic resins have been proved to improve fire reaction properties significantly, in order to fulfill fire resistance requirements, there is a need to develop adequate fire protection systems to allow the use of GFRP profiles in buildings and other applications. Laboratory tests are the primary way of studying the problem, but their applicability is limited due to the high number of parameters involved in the study, such as the geometry of the profile, type of protection system (active or passive), number of exposed faces to fire, applied load, etc.
In the present work, we develop a numerical model capable of accurately predicting the temperature distribution and the mechanical response of tubular section profiles made of GFRP, including the possibility of incorporating fire protection systems. Its main ingredients are:

(i) A thermal 2D model that predicts the temperature distribution inside the GFRP profile when exposed to fire in different scenarios, including conduction and natural convection of air and the internal radiation inside the cavity walls of the GFRP profile. The material decomposition is introduced by an Arrhenius equation. It is a non-linear, time-dependent coupled thermal/fluid dynamics/radiation problem;

(ii) The mechanical response of the GFRP profile is found by considering a geometrically exact large strains shells model with thickness variation, whose pure 3D constitutive model includes fiber orientation effects, thermal expansion, decomposition degree, and creep behaviour.
