Numerical investigation of bubble dynamics and flow boiling heat transfer in cylindrical micro-pin-fin heat exchangers (2024)
Journal Article
El Mellas, I., Samkhaniani, N., Falsetti, C., Stroh, A., Icardi, M., & Magnini, M. (2024). Numerical investigation of bubble dynamics and flow boiling heat transfer in cylindrical micro-pin-fin heat exchangers. International Journal of Heat and Mass Transfer, 228, Article 125620. https://doi.org/10.1016/j.ijheatmasstransfer.2024.125620

Micro-pin-fin evaporators are a promising alternative to multi-microchannel heat sinks for two-phase cooling of high power-density devices. Within pin-fin evaporators, the refrigerant flows through arrays of obstacles in cross-flow and is not restric...

Coupled atomistic–continuum simulations of nucleate boiling (2024)
Journal Article
Gennari, G., Smith, E. R., Pringle, G. J., & Magnini, M. (2024). Coupled atomistic–continuum simulations of nucleate boiling. International Journal of Thermal Sciences, 200, Article 108954. https://doi.org/10.1016/j.ijthermalsci.2024.108954

Boiling is a striking example of a multiscale process, where the dynamics of bubbles is governed by the interplay between the molecular interactions responsible for nucleation, and the macroscale hydrodynamic and thermal boundary layers. A complete d... Read More about Coupled atomistic–continuum simulations of nucleate boiling.

Understanding Inconsistencies in Thermohydraulic Characteristics Between Experimental and Numerical Data for DI Water Flow Through a Rectangular Microchannel (2024)
Journal Article
Schepperle, M., Samkhaniani, N., Magnini, M., Woias, P., & Stroh, A. (2024). Understanding Inconsistencies in Thermohydraulic Characteristics Between Experimental and Numerical Data for DI Water Flow Through a Rectangular Microchannel. ASME Journal of Heat and Mass Transfer, 146(3), Article 031801. https://doi.org/10.1115/1.4064330

Facing discrepancies between numerical simulation, experimental measurement, and theory is common in studies of fluid flow and heat transfer in microchannels. The cause of these discrepancies is often linked to the transition from the macroscale to t...
