The Use of Organic Rankine Cycles for Recovering the Heat Lost in the Compression Area of a Cryogenic Air Separation Unit

open access: yesEntropy, 2022
The use of organic Rankine cycles (ORCs) is a viable solution for the recovery of waste heat. For an air separation unit (ASU) with a production of V˙O2=58300mN3/h operating in Romania, the value of utilization of the heat transferred to the cooling ...

Exergetic Analysis of a Cryogenic Air Separation Unit

open access: yesEntropy, 2022
This case study analyzes a cryogenic air separation unit (ASU) with a production of V˙O2=58,300 [m3Nh] of gaseous oxygen with a concentration greater than 98.5%, operating in Romania on a steel plant platform.

High-Speed Temperature Measurement [PDF]

open access: yesEPJ Web of Conferences, 2022
In certain applications where temperature changes rapidly, e.g., compressor cylinder or explosion chamber, it is necessary to obtain temperature data with a sample rate high enough to register the change, i.e., the temperature probe response time must be

Optimal computer folding of large RNA sequences using thermodynamics and auxiliary information

open access: yesNucleic Acids Res., 1981
This paper presents a new computer method for folding an RNA molecule that finds a conformation of minimum free energy using published values of stacking and destabilizing energies. It is based on a dynamic programming algorithm from applied mathematics,

Algorithmic thermodynamics [PDF]

open access: yesMathematical Structures in Computer Science, 2012
Algorithmic entropy can be viewed as a special case of the entropy studied in statistical mechanics. This viewpoint allows us to apply many techniques developed for use in thermodynamics to the subject of algorithmic information theory. In particular, suppose we fix a universal prefix-free Turing machine and letXbe the set of programs that halt for ...

Energy and exergy analysis of a flat plate collector using collector test equations [PDF]

open access: yesE3S Web of Conferences, 2020
This paper presents the energetic and exergetic analysis of a widely used flat plate collector based on the collector testing equations. The evaluation of the performances of the collector is done under the climatic conditions corresponding to a typical ...

Higher derivative corrections to near-extremal black holes in type IIB supergravity [PDF]

open access: yes, 2006
We discuss string theory alpha' corrections to charged near-extremal black 3-branes/black holes in type IIB supergravity. We find that supersymmetric global AdS_5 x S^5 geometry is not corrected to leading order in alpha', while charged or non-extremal ...

Descriptive thermodynamics [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2006
Thermodynamics (in concert with its sister discipline, statistical physics) can be regarded as a data reduction scheme based on partitioning a total system into a subsystem and a bath that weakly interact with each other. The ubiquity and applicability of the scheme chiefly derives from that of partitioning protocols in experiments and observations ...
