Introduction and Motivation• Why is the research needed?• What started this project
***
• Designing an efficient HVAC pipe work system is a complex process.
• It requires a thorough understanding of pipe performance to produce a nearer alternative to the optimum design.
Literature Review
Experiment Study of Steel
Pipe
• Heat Transfer Calculation• Pressure Calculation• Corrosion Calculation
BIM
• BIM - AEC - HVAC• Autodesk - Revit• Data to BIM Model
VR Visualisation
• Real Time Rendering -Game Engine – Unity – Unreal –String Ray• Application programming interface (API)• Programing Language – C#, Python,
Gaps in literature review• Lack of knowledge on how the performance of the pipe
system has been evaluated by stakeholders.• Limited information on pipe performance simulation .• Absence of studies focusing on how modern technology
can be implemented on BIM revolution.
Research QuestionDeveloping intelligent and interactive HVAC pipe network
Research AimVisualize the dynamic performance of HVAC system pipework and investigate the possibility of using existing VR technology.
Research Objectives • To create VR models of Tata Steel pipe rigs,
which can be used for training and visualization purpose.
• Collect experimental data to embed in the model• Identify method to link data to back and forth
from BIM• Draw a set of Standard or Guidance of this
process• Study of practical implementation.
Research design
Heat transfer
Pressure and flow
Corrosion
Issues with BIM – PipeworkIncorrect product details, as well as:• Wrong tube standards referenced• Wrong tube sizing• Jointing ignored• Other fittings ignored
Poor understanding of flow, heat, pressure and service life conditions, such as corrosion
Research MethodologyThe research methods used to answer the main aim involve three tasks
Task - 1• A 3D model of a pipe network as a
case study. Ideally this should be a realistic 3D model of the pipework in BIM. This pipe network model should include all necessary parameters each as the diameter of each pipe, material of construction, flow rate, temperature, pressure, etc.
BIM Modeling
Tool
Task - 2• Computer program. Different
parameters can be changed and the resulting corrosion effect will be the output. Multiple corrosion models could be built so that the architect and engineer could choose whichever is appropriate. The project should begin with some simple equations that are already available in the literature.
Task - 3• A game engine with the 3D pipe
network imported which allows interaction with each pipe object.
