The Building That Teaches: Exploring Augmented Reality Affordances in Academic Incubators

open access: yesJournal of Interior Design, EarlyView., 2022
ABSTRACT Efforts to enhance the experience of interior environments have led to experimentation with augmented reality (AR) technology to encourage users to participate in the built space using their mobile devices. To investigate the role of AR technologies in interior design experiences, we highlight the interdisciplinary design of a mobile AR ...

Thermal Characteristics Investigation of the Internal Combustion Engine Cooling-Combustion System Using Thermal Boundary Dynamic Coupling Method and Experimental Verification

open access: yesEnergies, 2018
The engine cooling system must be able to match up with the stable operating conditions so as to guarantee the engine performance. On the working cycle level, however, the dynamic thermo-state of engines has not been considered in the cooling strategy ...

Heat transfer analysis of piston cooling using nanofluids in the gallery

open access: yesMicro & Nano Letters, 2015
Attaining proper temperature in engines is always a challenge for engine manufacturers primarily because temperature has a significant role in engine performance and emissions. With the development of new technology in the field of nanofluids, it seems very promising to use nanofluids as the coolant in internal combustion engines. In this reported work,
