Thermal Analysis Software Information

Thermal analysis software analyzes heat transfer processes and aids in their design. These processes are linear, non-linear, transient, and steady. The software provides solutions to methods, including conduction, convection, radiation, and changes of phase.

 

Thermal analysis programs offer functionalities such as modeling, editing, analyzing, and post-processing. It includes features such as geometry, broad-scale boundary conditions, and solver controls.

 

The programs give rise to several simulations, including:

 Temperature distribution thermal analysis simulation

  • Ablation conductors
  • Advanced convection
  • Temperature dependent properties
  • Contact mounting resistance
  • Heating caused by friction
  • Environmental effects on optical systems
  • Orbital heating
  • Phase change modeling
  • Radiation view factors
  • Steady state and transient heat transfer
  • Thermal structural coupling
  • Electro-upsetting simulation

A solution provided by the analysis proposes the means for maintaining the temperature of a particular material within a specific range for optimum performance. This objective is achievable by adding or removing heat from a system in a passive or active manner. Such activities are evaluated with the help of the software.

 

Types

 

The following are several categories of analysis performed today:

 

Dielectric: This technique is similar to the dynamic machine-driven mode. However, it integrates an oscillating electrical field rather than mechanical power. This type is beneficial for investigating adhesives, paints, composite substances, and thermosetting resin systems. An advantage of the method is its application on a laboratory scale and during tasks.

 

Differential thermal analysis: This method is associated with differential scanning calorimetry. Within this system, the subject and a reference material are exposed to the same form of thermal cycles. Any temperature fluctuations between the two elements are recorded. The next step is to plot this difference against time or temperature. Both exothermic and endothermic changes occurring in the experiment are detected this way. The data obtained through this approach relates to transformations such as glass transitions, crystallization, melting, and sublimation.

 

Differential scanning calorimetry: The subject and reference materials remain at equivalent temperatures at the start of the study. Care is taken to eliminate any deviation in the temperatures of both elements as the experiment progresses. After introducing heat, the technique measures the discrepancy in the quantity of heat required to raise the temperatures of the two substances. As a rule, a linear increase in the heat level of the sample takes place over time.

 

Dynamic mechanical: This approach enables the study and categorization of compounds. The dynamic mechanical method is suitable for analyzing polymers of a viscoelastic nature. Pressure is placed on the subject and the strain endured is determined. As the experiment progresses, varying degree of stresses and temperatures are introduced in the system. The technique identifies the temperature giving rise to a material's transition into glass. It is capable of recognizing other changes as well.

The aerospace and defense industry employs thermal analysis software for several objectives. The programs benefit areas such as aircraft anti-icing, jet engines, nozzles, avionics, satellites, re-entry vehicles, missiles, and rocket motors. Simulations provided by the software helps the automotive industry in aspects, including exhaust, backlights, drivetrain, seals, disc brakes, and welding.

 

Thermal analysis programs offer a diverse set of advantages to the consumer products and packaging field. They assist in determining thermal cycling effects on cans and bottles, bottle filling,  in home appliances such as solar water heaters and ovens, and solar heating of buildings. In the electronics industry, the programs are involved with solder, silicon wafers, and exhaust systems. In the field of energy, they are helpful in work related to solar power plants, thermal electric coolers, pressure vessels, and heat pipes.
