Action and Entropy in Heat Engines: An Action Revision of the Carnot Cycle

چکیده
Despite the remarkable success of Carnot’s heat engine cycle in founding discipline thermodynamics two centuries ago, false viewpoints his use caloric theory linger, limiting legacy. An action revision Carnot can correct this, showing that flow powering external mechanical work is compensated internally with configurational changes thermodynamic or Gibbs potential working fluid, differing each stage quantified by as caloric. Action (@) a property state having same physical dimensions angular momentum (mrv = mr2ω). However, this scalar rather than vectorial, including dimensionless phase angle (@ mr2ωδφ). We have recently confirmed atmospheric gases their entropy logarithmic function relative vibrational, rotational, and translational ratios Planck’s quantum ħ. The principle shows maximum rate (puissance motrice) possible from reversible controlled difference temperature hot source cold sink: colder better. This between sink also controls isothermal variations which identified temperature-dependent but unequal exchanges. Importantly, engine’s inertia ensures performed adiabatically expansion all restored to fluid during adiabatic recompression, less net performed. allows both energy return values at beginning cycle, point strongly emphasized Carnot. Our equates calorique, non-sensible later described Clausius ‘work-heat’, exclusively negative (−G) field energy. complements sensible vis-viva molecular kinetic motion, its recognition should significance for designing more efficient engines better understanding Earth’s climates.

متن کاملAction mirroring and action understanding in children
The past decade has experienced an increasing interest in action underestanding and children’s mirroring of others’ behavior. Behavioral investigations have focused on the development and significance of mimicry, goal prediction and imitation. Others have focused on the neural basis of action mirroring, identifying particular electrophysiological markers or related brain regions. A vivid debate...
متن کاملAn Unusually Efficient Coupling of Carnot Engines
The heat engine, or related mechanisms, appears as an essential component in most models for self-organizing phenomena. Following the autopoietic-allopoietic classification used in Prigogine’s dissipative structures paradigm to discriminate heat engines in terms of the final use of the work by they produced, we introduce here an autopoietic coupling of heat engines as a possible model for the e...
متن کاملCarnot-Like Heat Engines Versus Low-Dissipation Models
In this paper, a comparison between two well-known finite time heat engine models is presented: the Carnot-like heat engine based on specific heat transfer laws between the cyclic system and the external heat baths and the Low-Dissipation model where irreversibilities are taken into account by explicit entropy generation laws. We analyze the mathematical relation between the natural variables o...
