In the adiabatic split the total entropy is kept constant in the mechanical phase instead of the temperature. This algorithm has been shown to be considerably more stable than the isothermal split for thermoplasticity (Armero and Simo, 1993). In this paper, we have chosen to use the ...
Computer-Aided Engineering (CAE) analysis for the Reaction Injection Molding (RIM) process is very useful to predict problems in design process. For the ac... D Kim,BO Rhee,ES Han - Antec 被引量: 0发表: 2015年 加载更多来源期刊 Computational Mechanics 研究点推荐 non-isothermal mold filling...
The first-order phase transition between two tetrahedral networks of different density—introduced as a hypothesis to account for the anomalous behaviour of certain thermodynamic properties of deeply supercooled water—has received strong support from a
The lattice constant of fcc copper as a function of temperature was obtained by equilibration for 250 ps at each temperature in the isothermal-isobaric ensemble using a thermostat and a barostat at zero pressure42. Annealing simulations were performed with the same boundary conditions as the 0...
Fig. 1. Crosslinking reaction process of polymer with phenol-formaldehyde. Most of the phenolic resin gels can tolerate temperatures generally below 120 °C. However, when the reservoir temperature is over 140 °C, the gel used in the experiments usually has a very high concentration of polymer...

Q1 Work for the following process ABCD on a monoatomic gas is View Solution Q2 Starting with the same initial conditions, an ideal gas expands from volume V1 to V2 in three different ways. The work done by the gas is W1 if the process is purely isothermal, W2...
they are attached to intrinsic properties that for the purposes of optimization of the operation regime can be considered as constant. The total entropy change in the thermodynamic universe is given by, so that(or) the reversible performance is recovered. The main energetic quantities are the refri...
As discussed in more detail below, the (physically) more general non-isothermal case is based on the free entropy (e.g., refs. 109,110,111). Under certain assumptions (e.g., gradient-free entropy independent of temperature:112), this more general formulation reduces naturally to one based...
