Optimal Design of a Dual-Pressure Steam Turbine for Rankine Cycle Based on Constructal Theory

Energies, 2022
A one-dimensional dual-pressure steam turbine (ST) model for the marine Rankine cycle is built in this paper. Based on constructal theory, the optimal design of the dual-pressure ST is performed with a fixed total volume of the high- and low-pressure STs.

Design Is Construction, Construction Is Design

She Ji: The Journal of Design, Economics, and Innovation, 2019
This is a commentary on Michael Lissack’s two-part article “Understanding is a Design Problem: Cognizing from a Designerly Thinking Perspective.” Lissack’s claim that cognition and meaning making can be understood as design processes is a reiteration of arguments already put forward by constructivist thinkers.

Design with Constructal Theory [PDF]

, 2008
Constructal theory is the view that the generation of “designedness” in nature is a universal (physics) phenomenon that can be based on principle (the constructal law): “For a finite-size flow system to persist in time (to live) its configuration must ...
