An experimental and theoretical analysis of vapor-to-liquid phase change on microstructured surfaces
(Elsevier, 2020-09)
In this work, an experimental and a theoretical study was carried out on condensation heat transfer on vertically aligned bare unstructured, micro V-grooved and square-grooved copper substrates. During the experiments, ...
Investigation of the effect of particle stability on the transport properties and thermal behavior of ethylene glycol-water/SiO2 binary nanofluids
(IOP Publishing, 2020-04-09)
Nanofluids (Nfs) are considered as an effective working media in different thermal processes. Over the years, much attention has been paid to the problem of nanoparticle stability in base fluids in an unconfined area of ...
Design sensitivity and optimization of powertrain mount system design parameters for rigid body modes and kinetic energy distributions
(Springer Nature, 2020-08-24)
This study evaluates the influences of the powertrain mount design parameters on the frequencies of powertrain rigid body modes and their kinetic energy distributions (KEDs), which play an important role in the low-frequency ...
Computer simulations of 4240 MOF membranes for H2/CH4 separations: insights into structure–performance relations
(Royal Society of Chemistry, 2018-04-14)
Design of new membranes having high H2/CH4 selectivity and high H2 permeability is strongly desired to reduce the energy demand for H2 production. Metal organic frameworks (MOFs) offer a great promise for membrane-based ...
A prelude to the fundamentals and applications of radiation transfer
(Springer Nature, 2018)
Radiation transfer is one of the three pillars of heat transfer processes, along with conduction and convection. It is essential for any high-temperature industrial process taking place in combustion chambers, flames and ...
Boiling heat transfer enhancement of magnetically actuated nanofluids
(AIP, 2013)
Nanofluids offer a potential breakthrough as next-generation heat transfer fluids since they offer exciting new possibilities to enhance heat transfer performance compared to pure liquids. A major drawback for using ...
Steady and unsteady air impingement heat transfer for electronics cooling applications
(ASME, 2013)
This paper focuses on two forced convection methods—steady jet flow and pulsating flow by synthetic jets—that can be used in applications requiring significant amounts of heat removal from electronics components. Given the ...
Low-loss optical switch using Brewster angle
(IEEE, 2011)
Fabrication and actuation errors of submicron silicon waveguide optical switches are reported to remain within sub-100 nm ranges. These errors cause high loss ruining the optical performance of the switches at the on-state. ...
A numerical study of a single unsteady laminar slot jet in a confined structure
(ASME, 2013)
With the inherit advantages of air cooling, jet impingement can produce a factor of two or higher heat transfer than conventional fan flow over bodies. Therefore, impinging jets can solve a number of electronics thermal ...
A preconditioned multigrid for simulation of atmospheric flow and wind turbine wakes
(Elsevier, 2015-11-20)
This paper demonstrates a low Mach number preconditioning formulation for high Reynolds number, low Mach number atmospheric flows. The preconditioning is implemented together with multigrid approach into a multistage solver ...
