Large Eddy Simulations of Flow over Additively Manufactured Surfaces: Impact of Roughness and Skewness on Turbulent Heat Transfer
Himani Garg, Guillaume Sahut, Erika Tuneskog +2
Additive manufacturing creates surfaces with random roughness, impacting heat transfer and pressure loss differently than traditional sand-grain roughness. We conducted high-fideli…

Effect of fiber curvature on gas diffusion layer two-phase dynamics of a proton exchange membrane fuel cell
Danan Yang, Himani Garg, Martin Andersson
The dynamics of two-phase flow within the cathode of a proton exchange membrane fuel cell, particularly in Gas Diffusion Layers (GDLs) with varying fiber curvatures, remain underex…

Numerical simulation of two-phase flow in gas diffusion layer and gas channel of proton exchange membrane fuel cells
Danan Yang, Himani Garg, Martin Andersson
Liquid water within the cathode Gas Diffusion Layer (GDL) and Gas Channel (GC) of Proton Exchange Membrane Fuel Cells (PEMFCs) is strongly coupled to gas transport properties, ther…
