1000 Islands Fluid Dynamics

Prof. Hanson attended the 1000 Islands Fluid Dynamics Meeting held near Gananoque, Ontario, with members of his research group including Vahid Nasr Esfahani, Hossein Khanjari, Tejas Alva, and Costa Kandias. The meeting hosted over 60 technical seminars on current research that was attended by academics from Ontario, Quebec, and the North East of the United States who work in the area of fluid mechanics and heat transfer.  A summary of the presentations by Hanson’s team is given below.

Vahid Nsar Esfanani: Comparative analysis of end conditions on vortex shedding from a circular cylinder in sub-critical flow

Tejas Alva: Plasma actuator body force using a phase resolved integral approach

Hossein Khanjari: Laminar boundary layer response to an impulse forcing by a spanwise array of plasma actuators

Costa Kandias: Analysis of an expanding corner flow with turning vanes

Mechanical Engineering Undergraduate Students headed to Michigan State University to compete in their first Human Powered Vehicle Challenge (HPVC)

On April 5th, thirteen students from Lassonde School of engineering headed over to Michigan State University to compete in their first Human Powered Vehicle Challenge(HPVC) organised by American Society of Mechanical Engineers(ASME).

These students worked hard over the last 8 months designing and building a vehicle. Capstone Team A was responsible for building the shell of the vehicle while Capstone Team M built the frame and drive train. The logistics and finances were handled by the executive members of the team, Affan Behzad(President) and Julia Delongis(Treasurer).

The team had to go through different challenges over the course of three days which included:

1) Full safety inspection that comprised of static judging, manoeuvrability, stopping distance, stability at different speeds and roll bar check that required inverting the vehicle with the largest rider buckled in.

2) Drag racing against other teams.

3) Endurance race which included a rumble strip, slalom, uphill, parcel pickup/drop-off and sharp turns. These obstacles repeatedly put the design to test over the course of two and a half hours.

After successfully completing all these challenges, the team received an overall rank of 34th among the 50 universities that were competing this year.

Lassonde Professor’s paper named influential by the Physics of Fluids Journal

Lassonde Professor Alidad Amirfazli’s paper Shedding of multiple sessile droplets by an airflow was recently marked as an influential work by the Physics of Fluids journal.  The paper featured work by Professor Amirfazli and Lassonde graduate students Aysan Razzaghi and Hossein Banitabaei.

This work illustrates how shedding of droplets can improve water management for fuel cells, as well as anti-icing for aircrafts and wind turbines.

“We have indirectly been able to probe the effect of the flow field around sessile droplets as relates to droplet removal, for the first time” said co-author Alidad Amirfazli. “We found the size of the droplets and the surface wettability didn’t have a significant effect on the shedding, which was unexpected.”

A summary of the article can be found here.

Masters student wins top prize for paper at CSME Congress

Lassonde Mechanical Engineering Masters Student Diego de Moraes, who is completing his studies under the supervision of Dr. Aleksander Czekanski, won the 3rd place in CSME Student Best Paper Competition that took place during the 2018 CSME International Congress at the Bergeron Centre last month.
His project is on computational modeling of metal additive manufacturing processes.  The title of his paper is “The Influence of Power Size and Packing Density on the Temperature Distribution in Selective Laser Melting.”
His paper was selected from over 100 papers by other researchers, of which only 10 were presented at the CSME congress.

Lassonde Graduate Studies Open House

Lassonde will be hosting an open house event on November 30, 2017 to share information about our graduate studies.  You can register here.


Congratulations Professors Amirfazli and O’Brien

Professors at York University’s Lassonde School of Engineering have been awarded more than $2.2 million in Discovery Grants from the Natural Sciences & Engineering Research Council of Canada (NSERC). The funds will help the researchers to further the knowledge of their respective fields for a period of five years.

In the 2017 competition, 100 per cent of the Lassonde professors who applied for a renewal and 80 per cent of the first-time applicants were successful. Recipients of the Discovery Grants are:


Alidad Amirfazli – Alidad Amirfazli, from the Department of Mechanical Engineering, is pursuing a research program titled “Fundamentals and Applications of Liquid Drop Interactions with Complex Surfaces” for which he has been granted $350,000.

Paul O’Brien – Paul O’Brien, from the Department of Mechanical Engineering, is developing transparent, selectively permeable heat mirrors for which he has been granted $120,000.

These grants – based on recommendations from peer review committees containing world experts in each of 12 science and engineering fields – typically last for five years. The NSERC Discovery Grants program is very highly valued within the Canadian research community.

NSERC provides the core funding and freedom so Canada’s best researchers can pursue their most promising ideas and breakthrough discoveries – world‑firsts in knowledge.

Engineering students learn about social aspects of engineering!

In the “Mechanical Engineering as a Profession” class taught by Prof. Amirfazli, 2nd year students have came up with creative ways of not only completing their coursework, but also have a broader impact outside of the classroom.  In one project students to reduce the stress in the work/study environment designed and promoted Yoga classes, which is now entering in its 3rd year of implementation throughout the Lassonde School of Engineering. In another project, as a part of its requirements, students developed a video to warn public of the safety hazards of wearing a headphone.
