Dr. Aryal’s Thermal Hydraulics (TH)/Computation lab involves the study of heat and mass transfer, and fluid mechanics processes that transport energy and mass in nuclear-mechanical systems and provide broad technical expertise to govern system performance and safety. Key sub-research areas include -modes of heat transfer (conduction, convection, radiation), phase change, single and multi-phase fluids, use of gas (HTGR), molten salt (MSR), and liquid metal coolants (LMFBR) in addition to the water in a conventional LWR reactor. The purpose is to establish a correlation between thermal and neutronic properties with dual mechanical and nuclear engineering expertise (dual degrees) to support the existing accident analysis capabilities. 

Computational tools include RELAP, CFD, MCNP, Scale, multi-physics, PRA, Mathematica, SAPHIRE, OpenBUGS, and Fusion 360. Dr. Aryal’s research focuses primarily on modeling and simulation of various small-scale reactor systems or components of a reactor, radiation shielding, medical imaging, nuclear security, and non-proliferation challenges. His lab will explore the use of radioisotopes in image reconstruction/imaging, and he has previously used Filtered Back Projection (FBP) to support real-time imaging of fuel pins and other structures during transient testing in the TREAT reactor, INL, as a part of the collaborative effort to restart TREAT. Another avenue of Dr. Aryal’s research is to study Radioactivity present in oil and gas. Naturally Occurring Radioactive Materials (NORM) possess a major challenge to public health and occupational concerns. There have not been enough radiological studies and consequently, there is a lack of supportive data. In addition, there is no universal medical surveillance program for low-level doses, and the research done to date has been preliminary in nature. This research helps to quantify, characterize, and formulate stringent regulations to ensure public safety. Any correlation between the occurrence of radionuclides and specific hydrocarbon formations will be beneficial for the local economy.

Currently, his research centers around creating renewable energy-focused engineering projects specifically tailored to the needs of historically underrepresented STEM students (women and minorities including African American, American Indian/Alaska Native, Hispanic, Native Hawaiian/Pacific Islander at Marymount University. He is open to collaborating with STEM and even with social sciences to the best of his knowledge.
