We recently demonstrated the reduction of unified continuum and variational multiscale formulation to a computationally efficient fluid-structure interaction (FSI) via three modeling assumptions pertaining vascular wall. Similar coupled momentum method introduced by Figueroa et al., resulting semi-discrete yields monolithically FSI system posed in an Eulerian frame reference with only minor mod...

Aerothermoelastic fluid–structure interaction (FSI) is a crucial problem in the design of supersonic and hypersonic vehicles, but modeling capabilities are many cases quite limited. Insufficient treatment FSI can limit options or lead to damage loss vehicles. To improve understanding such problems, we conducted experiments with thin panels flow wind tunnel H2K at DLR, Cologne, where both therma...

We recently derived the unified continuum and variational multiscale formulation for fluid-structure interaction (FSI) using Gibbs free energy. Restricting our attention to vascular FSI, we now reduce this arbitrary Lagrangian-Eulerian (ALE) by adopting three assumptions wall. The resulting reduced achieves monolithic FSI coupling in Eulerian frame through a simple modification of fluid boundar...

It has been shown through recent investigations in biomechanics, that marrow can play a critical role upon the cancellous bone behavior [1]. Besides its direct influence on the transport properties including pressure drop, shear dissipated energy and tortuosity of the bone geometry, the marrow is also responsible in transmitting and regulating the inter-lamellas pressure [2], due to external lo...

in order to evaluation of the relationship among protein markers and traits such as proline content variation, quantum efficiency of photosystem ii and field viability index, 20 genotypes of barely were studied in a randomized complete block design in the greenhouse experiment. plants were transferred to springhouse at the four leaf stage and were located at the temperature of 4°c for three wee...

Pulse wave imaging (PWI) is an ultrasound-based method for noninvasive characterization of arterial stiffness based on pulse wave propagation. Reliable numerical models of pulse wave propagation in normal and pathological aortas could serve as powerful tools for local pulse wave analysis and a guideline for PWI measurements in vivo. The objectives of this paper are to (1) apply a fluid-structur...

The authors present a thermally and dynamically coupled fluid–structure-interaction (FSI) model of thermoforming process variant along with simulation results. By purposeful arrangement the inlet nozzles, under consideration seeks to improve deformation behavior plastic sheet made polyvinyl chloride (PVC), ultimately leading more uniform wall thickness distribution. In order capture complex int...

Static Feature-specific imaging (SFSI) employing a fixed/static measurement basis has been shown to achieve superior reconstruction performance to conventional imaging under certain conditions. In this paper, we describe an adaptive FSI system in which past measurements inform the choice of measurement basis for future measurements so as to maximize the reconstruction fidelity while employing t...
