In this investigation for Expandable Pattern Casting (EPC) simulation, an algorithm was developed to calculate the gas pressure of the evaporated foam during mould filling. Also, the effect of backpressure evaporative foam ...

The closed-form solution of a three-dimensional line-of-sight guidance with a moving tracker is derived for an ideal case, in which a pursuer is always on the instantaneous line between the target tracker and the target. ...

This paper implements a derivative free optimization method called `Genetic Algorithm' to estimate the parameters of a four-wheel, three degrees of freedom vehicle handling model. At first the model is developed containing ...

Euler conservation equations, ideal gas state equations and simplified chemical kinetics models were used to simulate two-dimensional straight and baffled shock tubes. In a straight channel, detonation waves were initiated ...

This study is concerned with the general motion of a guided flexible launch vehicle idealized as a non-uniform beam under continuous thrust action. The governing equations of motion are derived following the Lagrangian ...

In this paper, a 3-D, unsteady vortex lattice model to compute aerodynamic coefficients, using time domain eigenmode analysis, is presented. A computationally efficient technique for constructing a reduced order model of ...

In this paper, heat and mass transfer phenomena occurring simultaneously in falling film generator of absorption chillers have been studied. The analysis is based on the laminar flow of an Li/Br solution over a horizontal ...

Using Helmholtz's decomposition theorem, the laws of balance of linear and angular momenta are restated as surface integrals over the closed surface of an arbitrary subregion in a continuum. Newton's law of action and ...

In this paper, results of a preliminary study on the feasibility of using an Active Tendon Control (ATC) mechanism for frame structures subject to earthquakes is presented. So far, the ATC mechanism has mainly been considered ...

In this paper, the temperature of a moving surface is determined with a moving, finite element-based inverse method. In order to overcome the ill-condition of moving inverse problems, three different conventional regularization ...

In this paper, an unsteady, two-dimensional solver is developed, based on Van Leer's flux splitting algorithm, in conjunction with the ``Monotonic Upstream Scheme for Conservation Laws (MUSCL)'' limiters for improving the ...

Collapse, defined as the additional deformation of compacted soils when wetted, is believed to be responsible for damage to buildings resting on compacted fills, as well as failure in embankments and earth dams. In this ...

In this paper, a framework for operation of hydropower reservoirs in Iran is discussed. A time decomposition approach, which breaks down the operation optimization problem to long, mid and short-term planning stages, is ...
