New Journal of Physics, 2014 We develop a formalism to describe the particle production out of equilibrium in terms of dynamical spectral functions, i.e. Wigner transformed Pauli–Jordanʼs and Hadamardʼs functions.

NUMERICAL SIMULATION OF FLUID FLOW BEHAVIOUR ON SCALE UP OF OSCILLATORY BAFFLED COLUMN [PDF]
Journal of Engineering Science and Technology, 2012 The fluid dynamics of oscillatory flow in a baffled column of 145 mm diameter was investigated numerically in this work. This numerical simulation was carried out by a 2D laminar unsteady solver using CFD package Fluent® 6.3. From the simulation, data on

Effective mixing due to oscillatory laminar flow in tubular networks of plasmodial slime moulds
New Journal of Physics, 2020 The plasmodium of the unicellular slime mould Physarum polycephalum forms an extended vascular network in which protoplasm is transported through the giant cell due to peristaltic pumping. The flow in the veins is always parabolic and it performs shuttle

The Improving the Thermal Performance of a Heat Exchanger using a New Passive Technology
Tikrit Journal of Engineering Sciences, 2023 In this study, the oscillation technique was applied in a multi-tube heat exchanger with baffles. The Nusselt number was investigated in the heat exchanger (HE) over a wide range of operating conditions, Reynolds number (Re =205-3200), and oscillatory ...

Heat transfer performance for batch oscillatory flow mixing [PDF]
Experimental Thermal and Fluid Science, 2002 Abstract Experimental heat transfer data is presented for two batch operations of oscillatory flow mixing. In one case fluid is oscillated within a baffled tube and in the second case baffles are oscillated within a process fluid. For both situations the heat transfer coefficient depends on the intensity of oscillation, and the energy performance of ...

Principle and application of bubble-based oscillation for fast mixing on microfluidic chip
AIP Advances, 2022 Mixing in microfluidic devices presents a challenge because of the laminar flow in microchannels. Here, we present an oscillatory-flow-based microfluidic mixer (OFBMM) in which fluids are subjected to a back-and-forth motion by utilizing a periodically ...
