Most large scale shopping malls in cosmopolitan cities are installed with smoke extraction. In this tutorial, we will explore the effectiveness of smoke extraction systems in terms of maintain clearence smoke layer hight and (ppm) for signicant toxic gases.

Fire sprinkler systems are nowadays commonly installed in our building permises. In this tutorial, we will explore the effectiveness of spinkler systems from a fire modelling standpoint. Additionally, we can also look into the effect on water droplet size.

There is a handful of functions in fire modelling software. This is because fire is a complex phenomena and involves coupled simultaneous processes which can be controlled to some degree in fire modelling software. Let's introduce some of these features.

To model non-premixed diffusion flames (i.e. free-standing camp fire; fruniture fire, bushfire, etc), it is typical to couple the combustion models with turbulent effects, this video demonstrates the concept of turbulent combustion.

Most fire involves the burning of solid fuels, it is essential to utilise pyrolysis modelling techniques to describe the solid decomposition process. Meanwhile, aptly predicting the elevating gas volatiles will enable better prediction of soot partculates.

Egress route design is essential for every modern constructions. Let's have a look on the theory and developments of evacuation modelling. Thus, we can establish better understanding of how to combine CFD and evacuation models for ASET/RSET predictions.

Let's talk about Boundary Conditions in CFD from the basic priciples. We all know most engineering CFD problems involves inlet, opening/outlet and walls, but what do they do physically and numerically. Also, let discuss how to perform validation/verification.

Now, let's start with working on a simple clasic CFD example in ANSYS CFX/FLUENT. This case study will demonstrate the overall process from geometry, meshing, case setup, iteration and results plotting. We can also compare the results and software options.

One of the classical boundary flow problems in fluid mechanics is the 2D parallel plate problem. In this study, we can characterise the flow transition from laminar to turbulent. Additionally, we can non-dimensionalise the problem via data aquired in CFD. 

When it comes to classic CFD topics, characterising turbulent structures is one of the most famous problem to solve. In this case study, we are going to visualise turbulent vortex formation via studying the flow over a cylinder, looking at the tail  "vortex street".

We always talk about turbulence when it comes to fluid flows. However, what is the effect of turbulence towards the fluid properties? Through some classic fluid mechanics problems, we may find out via studying their flow structures.
