Julie Crockett

Julie Crockett came to BYU in 2007. She received her Bachelors degree in Mechanical Engineering from the University of Denver, and Masters and Ph.D. degrees from the University of California, San Diego. Her research interests are in areas of fluid dynamics, including environmental flows, which are often characterized by fluids of differing densities, and passive drag reduction mechanisms. She is interested in the effect of internal waves on global circulations in the ocean and atmosphere in addition to energy harvesting. She uses theory, computational fluid dynamics, experimentation, and ocean data as a part of her research. She has also spent time at sea collecting data for studying internal waves in the ocean.  She is also interested in the fundamentals of heat transfer through and flow dynamics over micro-structured surfaces which have the capability of reducing friction drag.

Fluid Mechanics, Environmental Fluid Dynamics, Computational Methods and Analysis

Professor Crockett is interested in flows of stratified fluids, including the propagation and breaking of internal waves in the ocean and atmosphere. These waves affect the general circulation of the ocean and the global balance of the ocean and atmosphere.  These circulations also affect winds at the surface which may be available for harvesting energy through effective wind turbine design.

She is also interested in the fundamental fluid dynamics and heat transfer properties of passive drag reducing mechanisms, specifically micro-structured surfaces.

Fluid Mechanics, Environmental Fluid Dynamics, Computational Methods and Analysis

Professor Crockett is interested in flows of stratified fluids, including the propagation and breaking of internal waves in the ocean and atmosphere. These waves affect the general circulation of the ocean and the global balance of the ocean and atmosphere.  These circulations also affect winds at the surface which may be available for harvesting energy through effective wind turbine design.

She is also interested in the fundamental fluid dynamics and heat transfer properties of passive drag reducing mechanisms, specifically micro-structured surfaces.

Julie Crockett came to BYU in 2007. She received her Bachelors degree in Mechanical Engineering from the University of Denver, and Masters and Ph.D. degrees from the University of California, San Diego. Her research interests are in areas of fluid dynamics, including environmental flows, which are often characterized by fluids of differing densities, and passive drag reduction mechanisms. She is interested in the effect of internal waves on global circulations in the ocean and atmosphere in addition to energy harvesting. She uses theory, computational fluid dynamics, experimentation, and ocean data as a part of her research. She has also spent time at sea collecting data for studying internal waves in the ocean.  She is also interested in the fundamentals of heat transfer through and flow dynamics over micro-structured surfaces which have the capability of reducing friction drag.

Fluid Mechanics, Environmental Fluid Dynamics, Computational Methods and Analysis

Professor Crockett is interested in flows of stratified fluids, including the propagation and breaking of internal waves in the ocean and atmosphere. These waves affect the general circulation of the ocean and the global balance of the ocean and atmosphere.  These circulations also affect winds at the surface which may be available for harvesting energy through effective wind turbine design.

She is also interested in the fundamental fluid dynamics and heat transfer properties of passive drag reducing mechanisms, specifically micro-structured surfaces.
