Global non-equilibrium thermodynamics of stationary states applied to the Rayleigh-Bénard convection
Robert Hołyst, Paweł Jan Żuk, Konrad Giżyński +3
Classical thermodynamics describes physical systems in thermodynamic equilibrium, characterized in particular by the absence of macroscopic motion. Global non-equilibrium thermodyn…
Direction of spontaneous processes in non-equilibrium systems with movable/permeable internal walls
Robert Hołyst, Paweł Jan Żuk, Anna Maciołek +2
The second law of equilibrium thermodynamics explains the direction of spontaneous processes in a system after removing internal constraints. When the system only exchanges energy…
The first law of thermodynamics in hydrodynamic steady and unsteady flows
Konrad Giżyński, Karol Makuch, Jan Paczesny +3
We studied planar compressible flows of ideal gas as models of a non-equilibrium thermodynamic system. We demonstrate that internal energy of such systems in station…
Parameters of state in the global thermodynamics of binary ideal gas mixtures in a stationary heat flow
Anna Maciolek, Robert Holyst, Karol Makuch +2
We formulate the first law of global thermodynamics for stationary states of the binary ideal gas mixture subjected to heat flow. We map the non-uniform system onto the uniform one…
Modified Kirchhoff's Laws for Electric-Double-Layer Charging in Arbitrary Porous Networks
Filipe Henrique, Pawel J. Zuk, Ankur Gupta
Understanding the dynamics of electric-double-layer (EDL) charging in porous media is essential for advancements in next-generation energy storage devices. Due to the high computat…
Steady state thermodynamics of ideal gas in shear flow
Karol Makuch, Konrad Giżyński, Robert Hołyst +2
Equilibrium thermodynamics describes the energy exchange of a body with its environment. Here, we describe the global energy exchange of an ideal gas in the Coutte flow in a thermo…
Steady thermodynamic fundamental relation for the interacting system in a heat flow
Robert Hołyst, Karol Makuch, Konrad Giżyński +2
There is a long-standing question of whether it is possible to extend the formalism of equilibrium thermodynamics to the case of non-equilibrium systems in steady states. We have m…
Using Unused: Non-Invasive Dynamic FaaS Infrastructure with HPC-Whisk
Bartłomiej Przybylski, Maciej Pawlik, Paweł Żuk +3
Modern HPC workload managers and their careful tuning contribute to the high utilization of HPC clusters. However, due to inevitable uncertainty it is impossible to completely avoi…
Call Scheduling to Reduce Response Time of a FaaS System
Paweł Żuk, Bartłomiej Przybylski, Krzysztof Rzadca
In an overloaded FaaS cluster, individual worker nodes strain under lengthening queues of requests. Although the cluster might be eventually horizontally-scaled, adding a new node…
Impact of Asymmetries in Valences and Diffusivities on the Transport of a Binary Electrolyte in a Charged Cylindrical Pore
Filipe Henrique, Pawel J. Zuk, Ankur Gupta
Ion transport in porous media is present in a wealth of technologies, e.g., energy storage devices such as batteries and supercapacitors, and environmental technologies such as ele…
Divide (CPU Load) and Conquer: Semi-Flexible Cloud Resource Allocation
Bartłomiej Przybylski, Paweł Żuk, Krzysztof Rzadca
Cloud resource management is often modeled by two-dimensional bin packing with a set of items that correspond to tasks having fixed CPU and memory requirements. However, applicatio…
Thermodynamics of stationary states of the ideal gas in a heat flow
Robert Hołyst, Karol Makuch, Anna Maciołek +1
There is a long-standing question as to whether and to what extent it is possible to describe nonequilibrium systems in stationary states in terms of global thermodynamic functions…
Charging Dynamics of Electrical Double Layers Inside a Cylindrical Pore: Predicting the Effects of Arbitrary Pore Size
Filipe Henrique, Pawel J. Zuk, Ankur Gupta
Porous electrodes are found in energy storage devices such as supercapacitors and pseudocapacitors. However, the effect of electrode-pore-size distribution over their energy storag…
Continuous non-equilibrium transition driven by the heat flow
Yirui Zhang, Marek Litniewski, Karol Makuch +3
We discovered an out-of-equilibrium transition in the ideal gas between two walls, divided by an inner, adiabatic, movable wall. The system is driven out-of-equilibrium by supplyin…
Generalization of the Rotne-Prager-Yamakawa mobility and shear disturbance tensors
Eligiusz Wajnryb, Krzysztof A. Mizerski, Pawel J. Zuk +1
Rotne-Prager-Yamakawa approximation is one of the most commonly used methods of including hydrodynamic interactions in modelling of colloidal suspensions and polymer solutions. The…
