The Thermofluid Physics Lab studies flows containing droplets and bubbles (multiphase flows), gas-liquid interfaces, and how light propagates through living tissue. Its subjects include the flow immediately after a droplet impact, the ultra-high temperatures and pressures that arise inside microscopic bubbles, and waves and flows in the microscale world governed by molecular motion. Using precise experiments, large-scale numerical simulations, and mathematical theoretical analysis, the lab clarifies the mechanisms behind physical phenomena and aims to develop new technologies. The lab welcomes visits at any time from students in the Department of Mechanical and Intelligent Engineering and from students at other universities.

The Space Environment Systems Engineering Lab studies hybrid rockets, which combine a solid fuel with a liquid oxidizer. Because the fuel is plastic, there is no risk of explosion during manufacturing or storage, unlike solid rockets, which use explosive propellant, or liquid rockets, which use liquid hydrogen. To overcome the traditional weaknesses of low combustion efficiency and low thrust, the lab is working on two new types of hybrid rocket: the CAMUI type and the end-burning type. Since 2026, the lab has also started research on electric propulsion for use in space and on fuel ignition using plasma.

The Space Environment Applied Engineering Lab studies the fundamentals of combustion using microgravity, an environment with almost no gravity. By isolating ways of burning that cannot be seen in everyday life and examining them, the lab furthers the understanding of combustion science. It investigates the physics of fires that occur inside spacecraft and on the ground, and also works on ensuring safety, which is the main drawback of combustion. It also aims at applications to energy problems, such as controlling soot formation, stabilizing combustion, and using biomass fuels efficiently.

The Computational Fluid Dynamics and Space Transportation Engineering Lab studies numerical simulation of flows using computers. Its targets include a wide range of complex flows: turbulence, flows containing bubbles or sprays, combustion flames, and high-temperature gas flows around objects flying at high speed. The lab develops its own computational methods and software, aiming at predictions that are useful for machine design. Students connect from the lab to supercomputers at various institutions, and can experience everything from grid generation to computation and visualization of results.

The Heat Transport Systems Lab studies problems related to how heat is transferred and transported. The lab is developing methods for reliably carrying out the thermal design of microsatellites, which are small and whose temperatures change easily, in a short period of time. Its research also covers emitters that radiate heat only at specific wavelengths, and heat transfer in ice slurry, a mixture of ice particles and water. In April 2026, the lab changed its name to the Heat Transport Systems Lab.

The Quantum Beam Materials Analysis and Harsh-Environment Semiconductor Device Engineering Lab conducts materials research using neutrons and X-rays, and develops radiation-resistant semiconductor devices and radiation measurement instruments. The lab consists of two groups: the Ohnuma Lab (Quantum Beam Materials Engineering Lab A) and the Kaneko Lab (Harsh-Environment Semiconductor Device Engineering Lab). The Ohnuma Lab studies the structure of matter using neutron and X-ray beams, and also researches a cancer treatment that uses a compact accelerator (boron neutron capture therapy). The Kaneko Lab handles semiconductors from purification of raw materials through crystal growth to device fabrication, and currently focuses on developing diamond semiconductor devices for nuclear reactor accident response and decommissioning.

The Neutron Beam Applied Science and Engineering Lab studies techniques that use neutron beams to examine the inside of objects. From the changes that occur when neutrons pass through an object, the lab can examine the crystal structure of metals, the elements they contain, temperature, and more without destroying the object. Using the university's accelerator facility (Hokkaido University LINAC) and neutron source (HUNS), the lab covers everything from developing neutron sources and instruments to analyzing materials, cultural heritage objects, and food. In collaboration with companies, the lab also works on preventing malfunctions in semiconductors (soft errors) caused by cosmic rays.

The Plasma Environmental Process Lab studies how to put plasma to use in industrial and environmental technologies. Plasma is widely used in industry, for example in materials processing, but users often say it is "incomprehensible" or "impossible to control." The lab develops methods that use lasers to probe the inside of plasma, and works on technologies for producing ammonia and hydrogen as well as on reactions between liquids and plasma. Students are welcome regardless of their undergraduate field, and applicants to the graduate school from other universities or from advanced courses at technical colleges (KOSEN) are also welcome.

The Plasma Materials Engineering Lab studies the control and new applications of plasmas used in industry, as well as the behavior of hydrogen inside fusion reactor materials. It is hard to grasp the internal state of plasma, and to date plasma has been used largely on the basis of experience. The lab uses lasers to measure electron density and temperature in plasma, and works on optimizing plasmas such as those used as light sources for semiconductor lithography. The lab also investigates how much of the hydrogen isotopes that serve as fusion reactor fuel enters materials and how they move within them, and applies the findings to technologies for controlling hydrogen.

The Quantum Beam Applied Medical Engineering Lab studies how to use quantum beams and radiation in medicine. In cooperation with the Proton Beam Therapy Center and the Department of Medical Physics at Hokkaido University Hospital, the lab aims to realize next-generation diagnosis and treatment. The lab also actively pursues joint research with companies and advances technology development through industry-academia collaboration. The lab is run in close cooperation with the Radiological Medical Physics field of the Graduate School of Biomedical Science and Engineering, and graduate students from the Graduate School of Engineering and the Graduate School of Biomedical Science and Engineering work together with fourth-year undergraduates of the Faculty of Engineering.
