We're coming back from an insightful 2016 STAR Global Conference in
Prague that focused on discovering better designs, faster. It's
clear that the world of Computer-Aided Engineering (CAE) is
shifting from troubleshooting and verification towards using
modeling and simulation to drive innovation. Below are some
examples of conference presentations that leveraged HEEDS technology
to explore new concepts. As with each edition, we strive to bring
you useful articles and examples of how HEEDS is being used to help
engineers produce better products. Keep reading to learn more about
exciting HEEDS-related happenings.

Maximizing Efficiency
of Marine Propellers
Rolla
SP Propellers SA improved the efficiency of a propeller fin cap
system using STAR-CCM+® and Optimate+™(Powered by HEEDS). Boss caps
with fins are intended to recover energy that is lost from the hub
vortex generated by the propeller by redirecting the flux. Proper
design may also reduce damaging cavitation effects. Normally this
type of fin cap system is used on large, low-speed, container ships
with large propeller diameters and low shaft RPM. In this case, a
fast RPM propeller was studied. A fin cap was put after a Rolla
propeller and open water CFD simulations were carried out.
A design study was
performed to automatically vary 13 parameters representing the
geometry of the fins and cap in an effort to identify designs that
increased efficiency and reduced maximum turbulent kinetic energy
downstream of the propeller. The study resulted in a non-intuitive,
high-performing design. View the presentation from last month's 2016
STAR Global Conference in Prague.

Improving Heat Transfer in
Rectangular Ducts
Many
applications of industrial interest involve heat transfer across
rectangular ducts of high aspect ratio, for example, forced air
pins--fin cooling of electronic devices or liquid pins--fin cooling
for high power application (hybrid electric vehicles, gas turbine,
blades, etc). The design of these systems aims to provide high heat
transfer rates while maintaining low pressure drop. MBDA Missile
Systems used STAR-CCM+® to first validate against published
experimental data for rectangular ducts with staggered arrays of
short pin fins. Average Nusselt numbers and pressure drop were
shown to correlate well between simulation and experiment. HEEDS
technology was then used to perform direct design search on a
parametric heat exchanger in order to maximize heat transfer while
simultaneously minimizing pressure drop. Vie presentation from last
month's 2016
STAR Global Conference in Prague.

Improving Flow in an Airline
Low-Speed Wind Tunnel
Uniformity
and angularity are characteristics that define the quality of flow
in the test section of a wind tunnel. In RUAG Aviation's large,
low-speed wind tunnel (LWTE), a patchwork of meshes with different
porosities was installed in the third corner of the airline to
improve the flow homogeneity in the test section. A design study
was conducted to identify designs that would maintain flow quality
while minimizing pressure losses. STAR-CCM+® was used to simulate
the complete airline in conjunction with a porous baffle to model
the impact of the meshes. Optimate+™, based on HEEDS technology,
was used to modify the pressure drop across the porous baffle as a
function of position in the wind tunnel cross section to improve
flow uniformity and angularity while reducing pressure drop. The work
was presented at 2016
STAR Global Conference in Prague last month.

Exploring Design
Performance Relationships
Often, improvements to
the simplest things can have a big impact on your daily tasks.
There are many tasks we perform repeatedly when working with HEEDS,
and streamlining those saves time and reduces effort. HEEDS 2015.11
contains many enhancements focused on simplifying workflows and I
want to highlight a few that help in exploring design performance
relationships.
In this article, we highlight a few new features that
help you discover better designs, faster. Read

our training programs. Ron takes the time to provide some
thought-provoking ideas on expanding the usage of design exploration.
Error
Designs: Is it OK if Some Simulations Fail during a HEEDS Design
Study?
During a design exploration study, HEEDS makes
many calls to your simulation model to evaluate potential designs.
This means that your model needs to accurately predict design performance
values (objectives and constraints) over a wide range of inputs
(design variables). Most modern simulation models satisfy this
requirement without difficulty. Read more...
