Design of multifunctional lattice-frame materials for compact heat exchangers

Compact Heat Exchangers for Microturbines

With distributed power generation market, the most economical solution today is to generate power through small gas turbine systems, arbitrarily categorized as microturbines (5 – 200 kW) and miniturbines (200 – 500 kW). The thermal efficiency of such microturbines is about 20% or less if no recuperator is used in the system. Using a recuperator (regenerator can also be considered but has a numb...

Selection of Materials for Heat Exchangers

1 his paper provides a U-J;P,G work for selecting heat exchangers materials especially those used in nuclear power plants. Typical examples of materials selection for heat exchanger tubing of nuclear power plants and condensers are presented. The paper brings out also, the importance of continued intensive R & D in materials in order to enhance the reliability and reduce cost by improving upon ...

Computational design of multifunctional materials

We propose a general scheme for the computational design of new materials using density functional theory. We then apply the scheme to two classes of materials; ferromagnetic ferroelectrics and half-metallic antiferromagnets. Our first ‘‘designer’’ ferromagnetic ferroelectric has subsequently been synthesized and the predicted properties verified. Our computations on halfmetallic antiferromagne...
