Sarah Crosby

Project: Thermal Comfort in Buildings

Supervisors: Steven Rogak and Adam Rysaneks_crosby_photo

Sarah joined the Mechanical Engineering Department at UBC in 2016.  She received her M.Sc. in Engineering Mathematics and B.SC. in Mechanical Engineering from Alexandria University. Her M.Sc. research focused on the Mathematical Modeling and Numerical Analysis of Continuously Variable Transmission (CVT) Systems.

In 2011, she received her B.Sc. from Alexandria University with a graduation project entitled: “Computational Fluid Dynamics (CFD) Simulation of the Laminar Flow Technique in Operating Rooms Using FLUENT ANSYS”. The laminar flow technique was modeled in this specific type of clean room that supposed to have low level of environmental contaminants. The clean rooms have a wide range of applications in the fields that are very sensitive to environmental contamination; e.g. food industry, computer chip manufacturing and operating rooms. The flow of this high class clean room must be unidirectional, the exhaust grills positions along with the over pressurization of the operating rooms were optimized, in order to achieve reasonable velocity, temperature and humidity distribution.


She is currently working on a graduate research project in UBC, collaborating with AYO smart home company and Vanair Design. The project’s objective is to assess the ventilation effectiveness of an engineered sustainable pilothouse. The pilothouse is a zero net energy building that maintains high levels of livability, sustainability and energy efficiency. It is intended to address the needs for the First Nation communities where indoor humidity has produced famously unhealthy conditions.
