Ice Dendrite Growth Atop a Frozen Drop under Natural Convection Conditions

Crystals, 2022
Condensation frosting is a type of icing encountered ubiquitously in our daily lives. Understanding the dynamics of condensation frosting is essential in developing effective technologies to suppress frost accretions that compromise heat transfer and ...

Modelling of Physical Method for Tar Elimination from Producer Gas at Low Temperature

Chemical Engineering Transactions, 2021
Combining a methanation step with biomass gasification requires an intensive tar removal process that reduces its content down to 1 mg/Nm3. In this paper, low temperature processes are suggested for treating tar and reducing its content to the acceptable

Atomistic Description of Interdroplet Ice-Bridge Formation during Condensation Frosting

Langmuir, 2022
The propagation of frost in an assembly of supercooled dew droplets takes place by the formation of ice protrusions that bridge ice particles and still-liquid droplets. In this work, we develop a Kinetic Monte Carlo (KMC) model to study the formation kinetics of the ice protrusions.

Freezing propagation of condensate droplets at early stage of frosting on vertical hydrophobic surface

Case Studies in Thermal Engineering, 2023
As condensate droplets formed at the early stage of frosting are the foundation of frost layer growth, to study the freezing propagation of condensate droplets is of great significance to understand the frosting process.
