Numerical Study on the Effects of Water and Heat Transport on Two-Phase Flow in a Polymer Electrolyte Membrane Fuel Cell

Energies, 2022
A one-dimensional transient non-isothermal model was developed to study the two-phase flow phenomenon in a polymer electrolyte membrane fuel cell. The model focused on the phase change between vapor and liquid water, and the transport of oxygen, hydrogen,

Isotope physics of heat and particle transport with tritium in JET-ILW type-I ELMy H-mode plasmas

Nuclear Fusion, 2023
As part the DTE2 campaign in the JET tokamak, we conducted a parameter scan in T and D-T complementing existing pulses in H and D. For the different main ion masses, type-I ELMy H-modes at fixed plasma current and magnetic field can have the pedestal ...

On the issue of modernization of steam-gas power units [PDF]

E3S Web of Conferences
Combined cycle power plants are an efficient solution for combined heat and power generation; however, during the summer period, their electrical output decreases due to the high ambient air temperature at the gas turbine compressor inlet.

Simulating Nanoscale Heat Transport [PDF]

, 2015
In this book chapter we provide the definition of "Simulating Nanoscale Heat Transport", broadly regarded as modeling heat conduction beyond Fourier's law. We primarely focus on incoherent transport, which is dominated by scattering between phonons and the boundaries of a given material.

Investigation of container strength when fixed in an open wagon equipped with pneumatic bags

Acta Technica Jaurinensis
Ensuring the efficiency of railway transport in international traffic needs the development of combined transport systems. Container transportation is the most relevant among them. Containers are usually transported by rail on platform wagons. Along with
