Computational Fluid Dynamics (Primary faculty mentor: Dr. Stephen
Gent)
Objective: Computational fluid dynamics (CFD) has become increasing popular in
modeling fluid flow characteristics of engineered systems. CFD began predominantly in the
automotive and aerospace fields, but has extended to agricultural, marine, energy, and
environmental applications, to name a few.
The objective of the computational fluid dynamics research program in this REU is to
provide undergraduate students with opportunities to learn about simulation tools in the
context of engineering design and analysis. Students will learn (1) the capabilities and
limitations of high-fidelity computational fluid mechanics tools, (2) to develop and
structure theoretical and applied problems using CFD, and (3) to extend their knowledge of
CFD to new and interesting problems. Upon completion of the 8-week program, students
will be able to




Outline procedures for creating a CFD model and analysis,
Apply CFD software tools to real-world engineering problems,
Demonstrate the process for creating, analyzing, and interpreting a CFD model,
Analyze, interpret and critique a CFD model for its validity, utility, and value.
Program: One specific application of CFD is in the design and analysis of photobioreactors
for algae production. Producing biofuels and bioproducts from algae is viewed as a
potentially viable method of addressing our current energy needs from alternative fuels.
Algae are photosynthetic organisms, similar to plants. A photobioreactor (PBR) is a
controlled system, similar to a bubble column or air lift reactor that manages light, carbon
dioxide, and additional nutrients to grow algae. Photobioreactors have proven to be
successful in laboratory-scale scenarios; however, designing effective systems on a
commercial level has proven to be difficult. Our goal is to use CFD tools to improve our
understanding in bubble and water flow patterns, heat transfer effects, light effects, and
nutrient management within PBRs. The overarching goal of this research is to improve PBR
designs enhancing microalgae production for producing biofuels and bioproducts.
Possible research topics include:



Modeling and analyzing a photobioreactor system with an intermittent sparger
(carbon dioxide injector) along the length of the PBR and compare results to
previous work with a diffuser/sparger that is continuous along the length of the
PBR.
Modeling and analyzing a photobioreactor system with different sparger designs to
determine the impact each type has on test parameter(s) like flow pattern.
Modeling and analyzing the heat transfer effects of algae present within a system
and comparing these with current fluid mechanics and heat transfer models.

Modeling and analyzing the scalability characterisitcs of the photobioreactor system
and compare the results to systems considered for commercial practice.
Preferred Qualifications for Applicant: The CFD group will recruit students from a
variety of disciplines, e.g., mechanical, chemical, civil, agricultural, industrial engineering,
or a related discipline. An ideal student for the CFD group would have a fundamental
background on CAD modeling (Pro Engineer, Solid Works, etc.) as well as general
numerical and analytical experience.
