The plug flow reactor model (PFR, sometimes called continuous tubular reactor, CTR, or piston flow reactors) is a model used to describe chemical reactions in continuous, flowing systems of cylindrical geometry. The PFR model is used to predict the behavior of chemical reactors of such design, so that key reactor variables, such as the ...
Continuous stirred-tank reactor. The continuous stirred-tank reactor (CSTR), also known as vat- or backmix reactor, mixed flow reactor (MFR), or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering. A CSTR often refers to a model used to estimate the key ...
RELAP5-3D. RELAP5-3D is the latest in the RELAP5 code series developed at Idaho National Laboratory (INL) for the analysis of transients and accidents in water-cooled nuclear power plants and related systems as well as the analysis of advanced reactor designs. Developer (s) Idaho National Laboratory. Initial release. July 6, 1997. Stable release.
Image is rotating to more clearly show the saddle-like shape of the vapor–liquid equilibria. In statistical thermodynamics, the UNIFAC method (UNI QUAC F unctional-group A ctivity C oefficients) [1] is a semi-empirical system for the prediction of non-electrolyte activity in non- ideal mixtures. UNIFAC uses the functional groups present on ...
A chemical reactor is an enclosed volume in which a chemical reaction takes place. [1][2][3][4] In chemical engineering, it is generally understood to be a process vessel used to carry out a chemical reaction, [5] which is one of the classic unit operations in chemical process analysis. The design of a chemical reactor deals with multiple ...
It is often used to design large-scale measurements providing a significant time and cost savings to the community. LANL's latest version of the MCNP code, version 6.2, represents one piece of a set of synergistic capabilities each developed at LANL; it includes evaluated nuclear data (ENDF) and the data processing code, NJOY.
Nuclear microreactor. A nuclear microreactor is a plug-and-play type of nuclear reactor which can be easily assembled and transported by road, rail or air. [1] Microreactors are 100 to 1,000 times smaller than conventional nuclear reactors, and range in capacity from 1 to 20 megawatts, compared to 20 to 300 megawatts for small modular reactors ...
Attainable region (AR) theory is a branch of chemical engineering, specifically chemical reaction engineering, that uses geometric and mathematical optimization concepts to assist in the design of networks of chemical reactors. AR theory is a method to help define the best reactor flowsheet using graphical techniques for a desired duty or ...
