Flow Science releases new FLOW-3D software

Flow Science Inc. offers a distributed memory version of its FLOW-3D computational fluid dynamics software.

Distributed memory is a version of computer code that can be run on multiple computers to find a faster solution.

Flow Science says FLOW-3D/MP v3.0 provides engineers conducting flow analysis with shorter design cycles for simulating real-world manufacturing processes involving large flow domains with complex flow phenomena.

Boart Longyear offers sonic drilling

Boart Longyear Drilling Services offers sonic drilling technology for exploration and for grout curtain installations during rehabilitation of earthen dams and spillways.

Sonic drilling involves the use of high-frequency resonant vibration to advance a core barrel into a structure. The sonic drill loosens soil and allows the core barrel to advance.

Personnel can then install an outer casing and remove the core barrel. Sonic drilling technology also eliminates fluid circulation, avoiding hydraulic fracturing. This type of drilling is especially useful at sites with vulnerable infrastructure or sensitive soil conditions, says Boart Longyear.

The Seaeye Falcon ROV system weighs less than 220 pounds, and is about 3.46 feet long and 2.08 feet wide. The system can be used during inspection of reservoirs, dams, and penstocks.

The Seaeye Falcon features high-resolution video and profiling and navigation sonar. It can perform inspections of areas up to 3,150 feet, the length of the umbilical cable needed to operate the ROV. It is depth-rated to 1,000 feet, and can enter pipes as small as 2.1 feet in diameter.

Garlock offers system for shaft seals

Garlock Sealing Technologies has developed a leak-free rotary shaft sealing system, the HYDRA-JUST. The company says the system can replace mechanical seals in virtually any industrial pumping application.

Unlike mechanical seals and packing, the new product does not use water to lubricate seal surfaces. Rather, the HYDRA-JUST maintains a bearing relationship to the shaft face in the seal chamber while preventing the process media from migrating into the stuffing box. It creates a radial bearing-to-face seal, which can be less expensive and more cost effective than traditional mechanical seals, the company says.

HYDRA-JUST requires no start-up adjustments or special installation equipment, Garlock says. The system can be installed in less than 1 hour, whereas mechanical seals can take 2 Omega; to 3 hours or longer to install, the company added.
