Dr. Izadpanahi Successfully Defended His Ph.D. Thesis
Under supervision of Prof. Pezhman Mardanpour, Dr. Ehsan Izadpanahi successfully defended his Ph.D. thesis on February 13, 2020.
Dr. Izadpanahi joined Prof. Mardanpour’s team on January of 2016 and became a PhD candidate in 2017. During his candidacy, he worked on projects funded by U.S. Air Force Office of Scientific Research (AFOSR), and U.S. Department of Transportation (USDoT). His Ph.D. thesis entitled “Constructal Design and Aeroelastic Stability of HALE Aircraft” led to 15 peer-reviewed journal papers in prestigious journals such as American Institute of Aeronautics and Astronautics (AIAA) Journal, Journal of Aircraft, Journal of Sound and Vibration, Journal of Applied Mathematical Modelling, Journal of computers and Fluids, and International Journal of Thermal Science.
Among his articles, the “Constructal Design of Aircraft: Flow of Stresses and Aeroelastic Stability” published by AIAA Journal presents an influential stepping-stone fundamental science in the field of design of aerospace vehicles. He also co-authored one book chapter and 7 conference proceedings.
Dr. Izadpahani’s Ph.D. Thesis Defense: Prof. Pezhman Mardanpour (Major Advisor), Profs. Cesar Levy, Charlie Lin, Sakhrat Khizroev, Ibrahim Tansel (Committee Members).
The National Science Foundation sponsors Professor Mardanpour’s research:
Prof. Mardanpour seeks to answer one of the most fundamental question in nature: Why do trees, rivers, nerves, etc. have curved and twisted branches? The hierarchical (i.e., few large & many small) or so-called tree-like architectures in nature are not straight lines. They evolve with twist and curvature to facilitate what flows through them.
The ultimate goal of Prof. Mardanpour's research is to explore and envision this phenomenon "predictively." This analysis and design theory stems from the Constructal Law of nature. It offers a rigorous strategy for meeting the challenge to scale up (i.e., add complexity to) designs that work in simple systems so they can persist over time amid technological evolution.
The National Science Foundation awards a grant to support Prof. Mardanpour's project entitled "Constructal Theory for Evolutionary Design of Twisted Paths in Heat Transfer Network."

Prof. Mardanpour talks about “Constructal Design of Flying Wing Aircraft.” in Constructal Law & Second Law Conference in Porto Alegre, Brazil
"The Constructal Law governs the phenomena of design and evolution in nature. The conference explores the unifying power of the Constructal Law and its applications in all the domains of design generation and evolution, from biology and geophysics to social organization, energy sustainability and security.
The conference also covers the Second Law, and how the Constructal fits in Thermodynamics. The Constructal Law and Second Law are self-standing as first principles. Together, they empower Science much more than the Second Law alone. CLC2019 is the 12th Conference will be hosted by Universidade do Vale do Rio do Sinos, São Leopoldo, RS, Brazil". Read more.

Constructal Design of Aircraft: New Fronts of Research Using Constructal Law
"Body-freedom flutter characteristics of flying wing aircraft vary with engine placement. Here, we show why a certain design parameter (engine placement) influences the aeroelastic flight envelope of the aircraft. The approach is based on the constructal law and the principle that a design that avoids stress strangulations provides better access to the flows that inhabit the system. This is in sharp contrast with trial-and-error techniques such as optimization, which means to opt from among different choices, cases, and designs. Under the same flight condition, the flow of stresses through the aircraft wings is investigated for several configurations including those with maximum and minimum flutter speed.
The results reveal that when the stresses flow smoothly in the wings the stability of the aircraft improves. On the other hand, in the cases in which the engine location causes stress strangulation, the flutter speed decreases considerably. The most severe stress strangulation corresponds to the aircraft configuration with minimum flutter speed (i.e., engine placement at 20% span behind the reference line.
The smoothest flow of stresses happens in the configuration with maximum flutter speed (i.e., engine placement at 80% span forward of the reference line)". Read more.
