CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

VLSI Bluetooth baseband controller.pptx
1. MODULE 3- Architectural support for system
Development
TOPIC : VLSI Bluetooth Baseband Controller
2. VLSI Bluetooth Baseband Controller
● Bluetooth is a standard for wireless data communication for the
2.4GHz ISM Band ( Industry, science and Medicine) developed by a
consortium of companies includes Ericsson, IBM, Intel ,Nokia and
Toshiba.
● The standard is intended to support short range communication
(10cm to 10m range) similar to the infrared communication using the
IrDA standard
● Bluetooth is intended to support laptop to cellular telephone, printer,
PDA, desktop and Fax machines, keyboard and so on.
● It can also provide a bridge to existing data networks.
● It supports a gross data rate of 1Mbit.s, and uses a frequency hopping
scheme and forward error correction to give robust communication in
a noisy and uncoordinated environment.
3. VLSI Bluetooth Baseband Controller- Bluetooth Piconet
● The Ericsson- VLSI Bluetooth baseband controller chip is a jointly
developed standard part which is intended for use in portable
bluetooth based communication devices .
● Bluetooth units dynamically form ad hoc ‘Piconets ‘ which are groups
of two to eight units that operate the same frequency- hopping
scheme.
● All of the units are equal peers with identical implementations, though
one of the units will be operate as master when the piconet is
established .
● Multiple Piconets can be linked to form a Scatternet
5. Bluetooth Controller Organization
● The chip is based around a synthesized ARM7TDMI core and includes 64
Kbytes of fast on-chip SRAM and a 4Kbyte instruction cache.
● Critical routines can be loaded in to the RAM to get the best performance.
● The cache improves the performance and power efficiency of code resident in
the off-chip memory.
● There is a set of peripheral modules which share a number of pins, includes
three UARTs, a USB interface and I2C bus Interface.
● FIFO buffers decouple the processor from having to respond to every byte
which is transferred through these interfaces.
6. Bluetooth Controller Organization
The external bus interface supports devices with 8 and 16 bit data buses and
has flexible wait state generations.
The counter timer clock has three 8 bit counters connected to a 24 bit
prescalar , and an interrupt controller gives control of all on- and off- chip
interrupt services.
7. Ericsson Bluetooth Core
The Bluetooth baseband controller includes a power optimized
hardware block, the Ericsson Bluetooth core (EBC), which handles all
the Link Controller functionality within the Bluetooth specification and
includes the interface logic to a Bluetooth radio Implementation.
The EBC performs all the packet handling functions for point to point ,
multislot and point to multipoint communications.
The baseband protocol uses a combination of circuit and packet
switching .
Slots can be reserved for synchronous channels, ex.. To support
voice trasmission.
8. Power Management
The chip has four power management modes:
1.Online: all blocks are clocked at their normal speed. The ARM7TDMI
core clock is between 13 and 40MHz, depending on the application.
2.Command: The ARM7TDMI clock is slowed by the insertion of wait
states.
3.Sleep: The ARM7TDMI clock is stopped, as are the clocks to a
programmable subset of the other blocks. The current drawn in this
mode is around 0.3mA.
4.Stopped: The clock oscillator is turned off.
10. Bluetooth system
The baseband controller chip requires an external radio module and
program ROM to complete the system.
The high level of integration leads to a very compact and economic
implementation of a sophisticated and highly functional radio
communication system.
12. Bluetooth silicon
The die area is dominated by the 64Kbyte SRAM, with the
synthesized EBC being the second largest block.
The synthesized ARM7TDMI core in the top-right corner of the chip
has far less visible structure than the ARM7TDMI hard macrocell.
This is because the hardcell was laid out by hand and manual
designers use very regular datapath structures to give dense layout
and to minimize the number of different cells that must be created.
Synthesized cell use less dense and less regular structures.
The advantage of the synthesized core is that it can be ported to a
new CMOS process much more rapidly.
13. Bluetooth silicon
The processor is capable of operating at up to 39MHz but the data
shown in the table are representative of a typical GSM application.
The Chip I/Os operate at 3.3V but the core logic typically operates at
2.5V .
14. Digital Radio
The advent of low cost high performance digital systems has enabled
radio communication to find new application areas as rapid growth of
the moble phone market.
Digital communication enables data to be sent in a form where most
errors caused by interference can be detected and corrected.
Digital technology also enables sophisticated radio techniques such
as frequency hopping to be controlled , further reducing the effects of
interference .
15. Digital Radio
Bluetooth extends this advantage to much smaller communication
networks and points to a future where not only the individual but also
all of their personal data appliances will be invisibly connected to each
other and to global networks.
16. Bluetooth system on chip
The Bluetooth application area has become a focus for activates
aimed at integrating digital and radio functions on to a single CMOS
chip.
The EBC block is also available as licensable intellectual properly for
use in other AMBA based designs.
