We present quantitative nano-scale analysis of the 3D spatial structure of an anticorrosive aluminium epoxy barrier marine coating obtained by ptychographic X-ray computed tomography (PXCT) [1-3]. We then use COMSOL Multiphysics® software to perform simulations on the acquired real 3D ... Per saperne di più

Baffle Design: Tube-in-Shell Electrical Gas Heaters

K. Lund[1], S. Lord[2]
[1]Kurt Lund Consulting, San Diego, CA, USA
[2]SML Associates, Encinitas, CA, USA

It is frequently necessary to electrically heat gases; a convenient geometry is the familiar tube-in-shell heat exchanger, where the tube side is modified for electrical heater-rods, and the baffled shell side contains the flowing gas, as indicated in Fig. 1. However, this modification ... Per saperne di più

Influence of Axial Conduction in the Design of a Compact Recuperator for Catalytic Combustor Based Portable Power Generation

A. N. Smith[1], H. Nochetto[2], C. M. Waits[2]
[1]U.S. Naval Academy, Annapolis, MD, USA
[2]U.S. Army Research Lab, Adelphi, MD, USA

Catalytic micro-combustor represents an exciting area of research for portable power generation. Extensive research is being currently conducted on the design of the reactor and catalyst selection [1]. However another critical element of the design will be a recuperator to minimize ...
