Sulfuric acid condensation sink calculated for the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

The condensation sink is a measure of the sulfuric acid lifetime against condensation on preexisting aerosol particles. Dimensionally it is the inverse of a time (reported in per second) and it is calculated starting from the aerosol size distribution. A l ...

Numerical Simulations of Pulsating Heat Pipes, Part 1: Modeling

John Richard Thome, Jackson Braz Marcinichen, Philippe Aubin, Raffaele Luca Amalfi, Filippo Cataldo, Brian Paul D'Entremont

The pulsating nature of a closed loop pulsating heat pipe (CLPHP) makes the prediction of its thermal-hydraulic performance extremely challenging. Unfortunately, the design of CLPHPs is still quite an empirical process, requiring testing of many prototypes ...

Modeling and optimization of an industrial ammonia synthesis unit: An exergy approach

An exergy modeling and optimization of an industrial ammonia unit based on steam methane reforming (SMR) process is presented. The base-case unit produces about 1000 t NH3/day [1], as well as power and steam, with no auxiliary exergy use. Some critical ope ...

Slow cooling and highly efficient extraction of hot carriers in colloidal perovskite nanocrystals

Michael Graetzel, Nripan Mathews, Mingjie Li

Hot-carrier solar cells can overcome the Schottky-Queisser limit by harvesting excess energy from hot carriers. Inorganic semiconductor nanocrystals are considered prime candidates. However, hot-carrier harvesting is compromised by competitive relaxation p ...

A method for taking into account seasonal storage in a district energy system optimisation problem

François Maréchal, Jessen Page, Jean-Loup Sylvain Robineau

In this work, a method for taking into account seasonal storage in an energy optimisation problem is developed. A master-slave optimisation procedure is applied, in which the master optimisation is an evolutionary algorithm, while the slave optimisation is ...
