Numerical solution of the PTT constitutive equation for unsteady three-dimensional free surface flows
(ELSEVIER SCIENCE BV, 2010)
This work deals with the development of a numerical technique for simulating three-dimensional viscoelastic free surface flows using the PTT (Phan-Thien-Tanner) nonlinear constitutive equation. In particular, we are ...
Spurious transients of projection methods in microflow simulations
(ElsevierAmsterdam, 2015-03)
The temporal behavior of projection methods for viscous incompressible low-Reynolds-number flows is addressed. The methods
considered result from algebraically splitting the linear system corresponding to each time step, ...
Determination of the bottom deformation from space- and time-resolved water wave measurements
(Cambridge University Press, 2017-11)
In this paper we study both theoretically and experimentally the inverse problem of indirectly measuring the shape of a localized bottom deformation with a non-instantaneous time evolution, from either an instantaneous ...
Continuous deposition of a liquid thread onto a moving substrate. Numerical analysis and comparison with experiments
(American Society of Mechanical Engineers, 2012-02)
The printing of a thin line of liquid onto a moving flat solid substrate was studied numerically. For a fixed value of the Capillary number, the window of steady state deposition was explored in terms of the substrate-nozzle ...
Thermodynamic analysis of direct steam reforming of ethanol in molten carbonate fuel cell
(Asme-amer Soc Mechanical Eng, 2008-05-01)
Fuel cell as molten carbonate fuel cell (MCFC) operates at high temperatures. Thus, cogeneration processes may be performed, generating heat for its own process or for other purposes of steam generation in the industry. ...
On non-ideal simple portal frame structural model: Experimental results under a non-ideal excitation
(Trans Tech Publications Ltd, 2004-01-01)
We present measurements of the non-linear oscillations of a portal frame foundation for a non-ideal motor. We consider a three-time redundant structure with two columns, clamped in their bases and a horizontal beam. An ...
An evaporative and desiccant cooling system for air conditioning in humid climates
(2005-07-01)
Evaporative cooling operates using water and air as working fluids. It consists in water evaporation, through the passage of an airflow, thus decreasing the air temperature. This system has a great potential to provide ...
Economic and technical feasibility study of a combined-cycle cogeneration system associated with cellulose plants
(1992-12-01)
In this paper, is presented an economical and technical feasibility study of a combined cycle cogeneration system proposed to be used in a pulp plant located in Brazil, where around 95% of country's pulp production is done ...
Dynamic behavior of naturally desiccated clays via resonant column testing at constant water content conditions
(2018-06-20)
The surficial soil at a western region of Bogota (Colombia) is a sedimentary deposit of high
compressibility lacustrine clays with lens of sand and peat and overconsolidation ratios (OCR)
from 1 to 9 due to desiccation ...
