Customarily, the LMTD correction factor, FT, is used to screen alternative designs for a heat exchanger. Designs with unacceptably low FT values are discarded. In this paper, authors have proposed a more fundamental criterion, based on feasibility of a multipass exchanger as the only criteria, followed by economic optimization. This criterion, coupled with asymptotic energy targets, provide the...

A generalized discriminant analysis based on a new optimization criterion is presented. The criterion extends the optimization criteria of the classical Linear Discriminant Analysis (LDA) when the scatter matrices are singular. An efficient algorithm for the new optimization problem is presented. The solutions to the proposed criterion form a family of algorithms for generalized LDA, which can ...

Abstract Topological optimization (TO) is commonly used to design a part for additive manufacturing (AM), but rarely entire systems including several parts. How can be optimized mechanical system in which each changes the boundary conditions? A Design method called TOMS (Topological Optimization of Mechanical System) has been developed take into account variation conditions when optimizing When...

The study proposes a technique for optimizing trihedral lattice tower structures from the condition of maximum critical load. Towers with cross section elements in form round pipes are considered. load is represented by horizontal concentrated force at upper end tower, simulating operation wind turbine. A constraint on constancy mass structure introduced. variable parameters width which varies ...
