Mechanically driven glassy systems and complex fluids exhibit a wealth of rheological behaviors that call for theoretical understanding and predictive modeling. A distinct feature of these nonequilibrium systems is their dynamically evolving state of structural disorder, which determines their rheological responses. Here we highlight a recently developed nonequilibrium thermodynamic framework i...
Identification of physical parameters for soft objects is important for surgical simulation, human modeling, and food engineering. In this paper, we propose an approach to estimate the physical parameters of uniform rheological deformation based on 2D/3D finite element (FE) model simulation. At first, the FE dynamic model was described and simulations were done with initial parameters. Then, th...
Rheological properties of pulp suspensions play a very important role in the industry, mainly due to the consumption of energy for transporting pulp among the different parts of the paper mill. In this work, we determined the rheology of longand short-fiber bleached kraft pulp suspensions by using a new rotational viscometer especially designed for their analysis. The experimental rheograms wer...
In this paper, preparation method of unsymmetrical di-methyl hydrazine with nano aluminum particles (50 and 130 nm) has been investigated. One of the important aspects of the research is the uniform dispersion of the nano particles in the fuel gel. Homogeneity of the fuel influences the quality of propellant combustion. The results showed that the combination of ultrasonic-mechanical-magnetic a...
