Three Dimensional Computational Study for Spiral Dry Gas Seal with Constant Groove Depth and Different Tapered Grooves
(
Elsevier Ltd
, 2013 , Conference Paper)
The three dimensional simulation for dry gas seal with constant depth spiral grooves and with different taper grooves is done using ANSYS FLUENT CFD code. Grid independence study and code validation are done with experimental ...
The probabilistic nature of ignition of turbulent highly-strained lean premixed methane-air flames for low-emission engines
(
Elsevier
, 2014 , Article)
The probabilistic nature of ignition of turbulent highly-strained lean premixed flames has been investigated. Two flow configurations have been considered in this study; counter-flow and bluff-body flames. Different ...
Numerical investigation of rotating stall in centrifugal compressor with vaned and vaneless diffuser
(
Science Press
, 2015 , Article)
This study presents a numerical simulation of the stall and surge in a centrifugal compressor and presents a descriptionof the stall development in two different cases. The first case is for a compressor with vaneless ...
Optimizing multi-objective dynamic facility location decisions within green distribution network design
(
Elsevier
, 2014 , Conference Paper)
Despite the surge of sustainable economic development which inspires corporations to optimize investment on environmental-friendly infrastructural facilities, limited pragmatic evidences are observed in product-service ...
Facility location decisions within integrated forward/reverse logistics under uncertainty
(
Elsevier B.V.
, 2014 , Conference Paper)
In this paper, a stochastic mixed integer linear programming (SMILP) model is proposed to optimize the location and size of facilities and service centres in integrated forward and reverse streams under uncertainty. The ...
Elastic properties of chiral, anti-chiral, and hierarchical honeycombs: A simple energy-based approach
(
Elsevier Ltd
, 2016 , Article)
The effects of two geometric refinement strategies widespread in natural structures, chirality and self-similar hierarchy, on the in-plane elastic response of two-dimensional honeycombs were studied systematically. Simple ...
Engaging Engineering Students in Active Learning and Critical Thinking through Class Debates
(
Elsevier Ltd
, 2015 , Conference Paper)
Within the program of engineering, typically there are courses that are heavily dependent on mathematics and derivations of fundamental concepts. A lot of active learning can be done in these classes by using the engineering ...
Large eddy simulation of surge inception and active surge control in a high speed centrifugal compressor with a vaned diffuser
(
Elsevier
, 2016 , Article)
In this study, we present a numerical investigation of active surge control and performance improvement for an aero engine centrifugal compressor (NASA CC3) using self-recirculating bleed slots with different bleeding ...
Time-domain simulation of second-order irregular wave diffraction based on a hybrid water wave radiation condition
(
Elsevier
, 2016 , Article)
A time-domain second-order method is presented to simulate three-dimensional wave–body interaction. In the approach, Taylor series expansions are applied to the free surface boundary conditions, and a Stokes perturbation ...
Random number of units for K-out-of-n systems
(
Elsevier
, 2017 , Article)
This paper takes up the reliability and preventive replacement problems for a K-out-of-n system, where K is a stochastic parameter provided. Firstly, we consider the case when K is predefined as constant numbers as is done ...
