Dr. Tarek Abdel-Salam
My research is focused in two areas: technical research in thermo-fluids and engineering education. My technical research includes computational fluid dynamics methods related to combustion processes, fuel injection, fluid flow and micro mixers, energy efficiency, renewable energy, and environmental management. In engineering education, my research includes areas related to recruitment to STEM fields, virtual engineering laboratories and distance education.
Dr. Randall Etheridge
My primary research interests are in the areas of agricultural and ecological engineering. A goal of my research is to increase the sustainability of the agriculture industry by reducing water use and improving the water quality leaving agricultural operations. In the field of ecological engineering, my research focuses on improving the design of coastal ecosystem creation and restoration projects to maximize nutrient retention while also providing other ecosystem services. My expertise includes high frequency measurement of nitrogen and phosphorus concentrations to improve the accuracy of water quality monitoring projects.
Dr. Praveen Malali
My research interests are in the areas of ocean-wave energy conversion and solar-thermal power generation. With an overall aim of increasing energy conversion efficiency while maintaining the structural integrity of the converter, I seek novel solutions to control aspects of single and multiple point absorber wave energy converters. Further, I want to explore new and efficient designs for the power take-off systems for wave energy converters. Another topic of interest to me is the sensitivity analysis and performance optimization of solar-heat engine cycles used in solar-thermal power generation.
Greening Coastal Vacation
Rental Properties (EPA, Source Reduction Program 2012-2015)
PI: Dr. Tarek Abdel-Salam
In this project 31 environmental
site audits of vacation rental homes were conducted in the vacation rental
dense communities of North Carolina’s Outer Banks and provide individual
written reports outlining cost effective pollution prevention and green
building recommendations based on the assessment of the rental property. Information
on the specific needs of coastal vacation rental properties were collected to
improve the NC GreenTravel recognition criteria for vacation rentals. Resources
specific to improving the energy efficiency and environmental performance of
vacation rentals were created. Property owners and vacation rental property
management businesses were offered relevant and applicable information to
improve the environmental performance of their properties.
Lean and Green at
North Carolina Wineries and Breweries: Putting Theory into Practice. (EPA, Pollution
Prevention Program, 2014-2017)
The project translates Lean and
Green principles to production practices by providing on-site pollution
prevention technical assistance for the craft brewing and small to medium
winery industry of North Carolina, both growing industries in the state. This
effort serves to reduce pounds of pollution, conserve water and/or energy,
reduce greenhouse gases, and save money through economy, energy, and environment
Greening of Food and Beverage Industries in North Carolina (EPA,
Pollution Prevention, 2016-2018)
This project will address one of the
P2 National Emphasis Area, “Food Manufacturing and Processing: Implement P2 projects to support more
sustainable food manufacturing and processing resulting in reduced greenhouse
gas emissions, water usage, hazardous materials generation and use, and/or
business costs.” The project will:
available specific technical assistance to food and beverage industries in
North Carolina seeking information about source reduction opportunities,
including providing on-site technical advice to assist in the development of
source reduction plans.
assistance to food and beverage industries in North Carolina for whom lack of
information is an impediment to source reduction.
training in source reduction techniques.
seminars/discussion sessions on pollution source reduction and production waste
Drivers of Storm water Flooding in Coastal Communities: A Citizen in Science
Project (NSF Eager grant)
The project will investigate the
coastal communities on Bogue Banks that frequently experience flooding after
significant precipitation events. Etheridge will work with town managers to
employ engineering solutions to alleviate the effects of storm water flooding
events using both scientists and citizens for data collection.
Participatory Mapping of
Surface Water Hydrology as an Initial Step in the Restoration of Lake
Mattamuskeet (DOI US Fish and Wildlife Service)
Lake Mattamuskeet is a natural
lake system located on the Albemarle-Pamlico Peninsula on the coast of North
Carolina. The 40,000-acre Lake Mattamuskeet is the centerpiece of the U.S. Fish
and Wildlife Service (USFWS) Mattamuskeet National Wildlife Refuge (NWR), which
provides habitat for wintering waterfowl and other migratory birds.
Mattamuskeet NWR annually supports a significant percentage of wintering
waterfowl in the Atlantic Flyway. Lake Mattamuskeet has historically contained
dense beds of submerged aquatic vegetation that provide food for swans, diving
ducks, and puddle ducks and important habitat for fish, but declines in water
quality are most likely the cause of recent reductions in submerged aquatic
vegetation coverage in the lake. The declining water quality and loss of
submerged aquatic vegetation are serious concerns to the citizens of Hyde
County and the Refuge. The resources, sport, and recreational opportunities
provided by Lake Mattamuskeet are important for the community and the local
Despite its status as a National
Wildlife Refuge, Lake Mattamuskeet has a long history of human alteration.
Understanding the causes and potential corrections for water quality concerns
is complicated because of the lake’s large surface area (41,000 acres), extensive
shoreline (72 miles), shallow depth (average of 1 meter), and long history of
hydrological alteration. In addition, many adjacent land owners farm and/or
manage duck impoundments that drain into the lake and can periodically be
flooded by the lake during times of high water. Agricultural production and the
waterfowl impoundments are vital to the area’s economy, but their impact on the
lake ecosystem is unknown.
The Refuge and community have an
immediate need to improve their understanding of the complex hydrology in the
region in order to develop a plan for improving water quality and restoring
submerged aquatic vegetation. Due to the flat landscape and the substantial
human alterations, understanding the hydrology in the watershed is nearly
impossible without community input. In addition, this project will seek input
from community members at the beginning of the solutions planning process as
any proposed changes must be sustainable for the lake and community.
Building Net Zero Energy Sustainable Communities (Constellation,
E² Energy to Educate grant)
PI: Dr. Ranjeet Agarwala
The program is for student
projects focusing on energy science, technology, and education. This project
will educate and inspire students on the significance and societal benefits of
sustainability and renewable energy in the preservation of environment and
natural resources through a hands-on solar technology project. Around 150
students from the College of Engineering and Technology (CET) will partner with
International Green Construction Code (IGCC) to develop and deploy renewable
energy sustainable systems with a goal to build a net zero energy facility.
