Quasistatic process - Wikipedia
In thermodynamics, a quasi-static process, also known as a quasi-equilibrium process (from Latin quasi, meaning ‘as if’ [1]), is a thermodynamic process that happens slowly enough for the system to remain in internal physical (but not necessarily chemical) thermodynamic equilibrium.An example of this is quasi-static expansion of a mixture of hydrogen and oxygen gas, where the volume of the ...
热力学中的可逆过程与不可逆过程 - 知乎 - 知乎专栏
这样一个过程称为准静态过程（quasistatic process），因为这一过程几乎处在完全不变的静平衡。 我们将会看到，在这一过程中热量虽然能被吸收或者放出，但仍然保持可逆性。
多载荷步下的准静态（Quasi-Static）结构分析 - 知乎
随着有限元分析技术的发展，工程师们已经不再满足于单步单载荷的 静力分析 了。 为了更好地了解系统的 结构动力学 特性，我们会采用 瞬态分析 方法。 瞬态有限元分析可直接计算输出结构动响应历程，但每个时间步输出一次全场应力和变形必然导致计算耗时长，结果文件过于庞大。
Quasi-static process: definition and examples - Solar energy
2024年4月18日 · In summary, the quasistatic process is a thermodynamic concept that provides a solid theoretical framework for the analysis of systems in equilibrium and the formulation of thermodynamic laws.
What's the significance of a quasi-static process?
2021年1月19日 · In a quasistatic process the system evolves from one state to another very slowly, so that it always remains in equilibrium (with negligeable corrections). The final state is thus an equilibrium state, and the process can be reversible (in principle, but it doesn't have to.)
2000年10月11日 · 6 2. Open, single phase, simple systems For an internally reversible, quasi-static process with one component entering and leaving the system, all intensive properties
Combined First and Second Laws 1. Closed, single phase, simple systems From the 1st Law: dE = dU = δ Q + δ W For an internally reversible, quasi-static process with only PdV work: δQ = δQ rev = Td S and δW = δWrev = − PdV Therefore, dU= TdS− PdV which also provides a way to determine entropy changes: Basis: 1 mole of ideal gas of constant Cp
6 Quasistatic thermodynamic processes • Quasistatic processes are processes that proceed slowly enough that the system is in internal equilib-rium. • p-V diagrams are a useful way to visualize quasistatic processes. • You should be able to compute change in internal energy, work done, and changes in entropy over a quasistatic process.
Quasistatic approximation - Wikipedia
In the most common acceptance, quasistatic approximation refers to equations that keep a static form (do not involve time derivatives) even if some quantities are allowed to vary slowly with time. In electromagnetism it refers to mathematical models that can be used to describe devices that do not produce significant amounts of electromagnetic ...
