Nuclear-fusion reactor smashes energy record Hacker News

ARC's volumetric thermal power density (volume of reactor, not of the plasma) is just 1/40th that of the primary reactor vessel of a commercial pressurized water fission reactor. 60% of the mass of an ARC reactor is in the steel structural supports for the magnets, so it's about at the upper limit for steady magnetic fields in a fusion reactor.

Fluid flow down a pipe requires a pressure gradient, i.e., a drop in pressure (pressure drop) down the pipe. For liquids, pressure drop costs money for pumping but doesn't affect reaction rates. For gases, pressure drop results in expansion of the gas and an increase in volumetric flow rate with position down the reactor.

In Post 1280 we used a correlation for the Fanning friction factor for turbulent flow in a pipe. For laminar flow (Re 3000), there is another correlation that is commonly used: \(f_F = 16/Re\). Unfortunately, the correlations for laminar flow and turbulent flow have different values at the transition that should occur at Re = 3000.

Sep 10, 2020 Plug Flow Reactors (PFRs) Another type of reactor used in industrial processes is the plug flow reactor (PFR). Like the CSTRs, a constant flow of reactants and products and exit the reactor. In PFRs, however, the reactor contents are not continuously stirred. Instead, chemical species are flowed along a tube as a plug, as shown in Figure 25.2.

Plug flow reactor model - Wikipedia

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 dimensions of the reactor, can be estimated.

The reactor is heated by high pressure steam which has a temperature of 470 K and is fed into the reactor at point 1 and leaves the reactor at point 2. The reactants flow through the tubes. Tubular reactors are used, for example, in the steam cracking of ethane, propane and butane and naphtha to produce alkenes.
