Dr. Vriend leads the Granular Flow Laboratory. She is an expert in performing detailed laboratory experiments and targeted field work involving particulate flows such as sand and snow. In addition, she also employs numerical simulations and theoretical modelling to complement observations, often in collaboration with scientists from multidisciplinary fields. She has active projects in granular rheology and avalanching, and dune structure and migration. In the past she worked on the dynamics of real snow avalanches, singing sand dunes, silo honking, and seismic wave propagation.

MCEN 3021 - Fluid Mechanics
Primary Instructor
-
Fall 2020 / Fall 2021 / Fall 2023
Examines fundamentals of fluid flow with application to engineering problems. Topics covered include fluid statics and kinematics, Bernoulli equations, laminar and turbulent viscous boundary layers, laminar and turbulent pipe flow, and conservation equations for mass, momentum and energy. Same as CHEN 3200 and CVEN 3313.
MCEN 5042 - Heat Transfer
Primary Instructor
-
Spring 2024
Studies development of equations governing transport of heat by conduction, convection, and radiation, and their solution. Includes analytical and numerical solution of initial and boundary value problems representative of heat conduction in solids. Describes heat transfer in free and forced convection, including laminar and turbulent flow. Also involves radiation properties of solids, liquids, and gases and transport of heat by radiation.
