Impact of Darcy–Forchheimer Inertial Drag and Heat Dissipation on Micropolar Hybrid Nanofluid Flow via Expanding Surface

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The hybrid nanofluid integrated with micropolar fluid shows growing interest due to the enhanced thermal performance in microscale devices. These improved properties are due to their greater thermal conductivity and rotational effects. The proposed study assesses the significance of velocity slip on the flow characteristic of micropolar ...

Bioconvection Darcy–Forchheimer Flow of Ree‐Eyring Nanofluid Over a Riga Plate With Arrhenius Activation Energy and Viscous Dissipation

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This work examines the intricate interactions of heat radiation, viscous dissipation, the Cattaneo–Christov thermal model, gyrotactic microorganisms, Arrhenius activation energy, and Darcy–Forchheimer flow affecting Ree‐Eyring nanofluid behavior across a Riga plate.

V1647 Orionis: One Year into Quiescence

, 2007
We present new optical, near-IR, and mid-IR observations of the young eruptive variable star V1647 Orionis that went into outburst in late 2004 for approximately two years. Our observations were taken one year after the star had faded to its pre-outburst

Influence of Zn2+ and Oxygen Supply on Malic Acid Production and Growth of Aspergillus oryzae

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Malic acid is a valuable platform chemical traditionally derived from fossil‐based resources. Microbial cultivation with Aspergillus oryzae offers a sustainable alternative based on renewable feedstocks. In this study, a well‐established minimal medium for malic acid production, commonly used in previous research to ensure reproducibility, was

Protoplanetary disc evolution and dispersal: the implications of X-ray photoevaportion

, 2017
(Abridged) We explore the role of X-ray photoevaporation in the evolution and dispersal of viscously evolving T-Tauri discs. We show that the X-ray photoevaporation wind rates scale linearly with X-ray luminosity, such that the observed range of X-ray ...

A Solution to the Protostellar Accretion Problem

, 2005
Accretion rates of order 10^-8 M_\odot/yr are observed in young protostars of approximately a solar mass with evidence of circumstellar disks. The accretion rate is significantly lower for protostars of smaller mass, approximately proportional to the ...
