Conditioning, Correlation and Entropy Generation in Maxwell's Demon
Maxwell’s Demon conspires to use information about the state of a confined molecule in a Szilard engine (randomly frozen into a state subspace by his own actions) to derive work from a single-temperature heat bath. It is widely accepted that, if the Demon can achieve this at all, he can do so without violating the Second Law only because of a counterbalancing price that must be paid to erase in...
متن کاملComputing Entropy: Understanding Maxwell's Demon
In 1871, James Clerk Maxwell proposed that a being, able to measure the microscopic parameters of a physical system and act accordingly, might be able to violate the Laws of Thermodynamics. The being became known as Maxwell's Demon. Investigations conducted over the course of a century have placed well-de ned thermodynamic bounds upon the action of Maxwell's demon. It is the purpose of this wor...
متن کاملMaxwell's Demon and the Entropy Cost of Information
We present an analysis of Szilard's one-molecule Maxwell's demon, including a detailed entropy accounting, that suggests a general theory of the entropy cost of information. It is shown that the entropy of the demon increases during the expansion step, due to the decoupling of the molecule from the measurement information. It is also shown that there is an entropy symmetry between the measureme...
متن کاملEntropy generation analysis of non-newtonian fluid in rotational flow
The entropy generation analysis of non-Newtonian fluid in rotational flow between two concentric cylinders is examined when the outer cylinder is fixed and the inner cylinder is revolved with a constant angular speed. The viscosity of non-Newtonian fluid is considered at the same time interdependent on temperature and shear rate. The Nahme law and Carreau equation are used to modeling dependenc...
متن کاملEntropy Generation In an Unsteady MHD Channel Flow With Navier Slip and Asymmetric Convective Cooling
The combined effects of magnetic field, Navier slip and convective heating on the entropy generation in a flow of a viscous incompressible electrically conducting fluid between two infinite horizontal parallel plates under a constant pressure gradient have been examined. Both the lower and upper plates of the channel are subjected to asymmetric convective heat exchange with the ambient fluid. T...
