Investigation of Microtubular Ceramic Structures
Abstract
Calculations and experiments were conducted to explore the feasibility of producing very compact high-temperature heat exchangers via microtubular ceramic structures. Such microtubular ceramic structures consist of multiple interconnected ceramic tubes with very thin walls, small diameters, and modest ratios of length to diameter. As a result, they should have reasonable strength, as well as very high specific area. The investigation included: calculations of expected volume requirements and heat-exchange performance for microtubular ceramic heat exchangers compared to one of conventional dimensions; experiments seeking to define means for preparing leak-tight microtubular ceramic structures; preliminary exploration of means to provide separate manifolds to the interior and exterior of the microtubes; and a leak test of one experimental manifold microtubular ceramic structure.
