Heatsink Selection for a MiniPC under Natural Convection

Demo of cooling of Raspberry Pi using the Immersed Boundary Method (IBM). 
IBM makes CAD cleanup and defeaturing obsolete. A CAD with detailed electronic features (pins, connectors, engravings, etc.) can be directly imported as is for simulation
In this demo a Raspberry Pi is overclocked and the heat transfer behaviour is compared for two cases where the fan is off and on.

Thermal simulation of electronics in a housing.

This project simulates a solid-state relay under a 15W heat load. 
This relay includes a heat sink that acts as a fixture from the relay housing to the mounting wall. The product is tested under natural convection conditions at 20C.

Testing two configurations for ventilation in a warehouse. Several heat sources are placed throughout the area. The objective is to evaluate how the different configurations perform in terms of predicted mean vote (PMV) & predicted percentage of dissatisfied (PPD). A total of 20 people (represented as cylinders) were placed inside of the warehouse.

Convective heat transfer analysis were carried out, with the radiation formulation on. By placing two simple outlets on the ceiling of the warehouse, ventilation was greatly improved and all 20 people were within the -0.5 to 0.5 PMV range.

Conjugate heat transfer is a behavioural analysis where convective (transfer between fluid) and conductive (transfer between solids) heat transfer takes place in a system. This combination of heat transfer has forced or natural convection where fluid is dominated by convection and solid is dominated by conduction. 
Objective of the Experiment is to
Carry out mesh Independent study
Stimulate CHT using two different processor materials
Carry out the analysis at different velocities 
To determine the hot spots and Heat transfer co-efficient at different velocities

Asses the external and internal fluid flow for a department store building.
Using the incompressible  steady state analysis to determine natural convection flow through the building and improve the ventilation through simple design changes.

This project is a brief, early-stage design simulation of a department store. The objective is to obtain very early insights of wind in the building as well as its surroundings. It is to ensure if there is optimum ventilation in all the floors of the building. Airflow is assumed to be in the direction of the main entrance to the store with a speed of  5 m/s ( 18 kmph).

Analysis of the thermal comfort in Pantheon.
1st study: Incompressible external flow simulation to find the air exchange rate
2nd study: Internal convection simulation inside the building

The presented project is an analysis of the thermal performance of a heat sink connected to chip. The chip acts as a power source generating 30W of heat. Using a conjugate heat transfer analysis allows for simulation of heat transfer between the solids via conduction and the dissipation of heat into the ambient fluid via convection. The components are cooled passively and buoyancy effects  drive the flow in the surrounding air.

The objective of this project is to evaluate the max temperature of the chip during operation and therefore a steady state analysis was carried out.
