    Best Ansys software for recreation of granulate flow

    Dear All, I am going to recreate the flow of a granulate material (approx. 0.5mm diameter particles) inside and under the hopper. The hopper is approx. 150mm high. I have access to the licensed Ansys software. I did a quick research to find out, which Ansys software would be the most suitable...

    Measure a pressure inside the tank of a cigarette lighter

    Dear All, Did you try to measure the pressure inside a cigarette lighter, a barbecue lighter or similar? I mean a gas-state fuel pressure in say half-full tank of a lighter. The typical valve of a lighter does not have a thread so we could firmly attach a pressure gauge. The pressure of the...

    Measure temperature through a transparent nylon material

    Dear All, I hope that you are ok. I need to measure the temperature of a steel product with an IR camera. The capacity of the camera is -20degC-350degC. I will keep the IR camera in a fixed position and will measure the steel product temperature. I will have 2 variables in this test: - The...

    Scan of a product with 3D CAD file as the outcome

    Hi, I have a device, which size is approx. 200mmx35mmx50mm. Inside the device, there are tens of little elements and compressed gas. I wondered whether it would be possible to scan this device with some technique, such as an X-ray, and obtain a 3D image of this device in a form of a 3D CAD...

    Thermal mechanical properties of pharma tablet or chew gum

    Dear All, I am looking for the thermal-mechanical properties of some pharmaceutical tablet, a chew gum, or similar. Specifically, I am looking for: - Density (kg/m3) - Specific heat (j/kg k) - Thermal conductivity (w/m k) - Viscosity (kg/m s) - Molecular weight (kg/kg mol) - Standard state...

    Modelling of tablets drying

    Dear All, I develop a model (in Fluent) that will simulate the drying process of a bunch of tablets stored in a chamber. Tablets are dried by the air that is pumped to the chamber (through a single inlet) and penetrates a perforation plate (on which tablets are put on) and then it penetrates...

    VFD for the air blower

    Dear All, I need to provide a source of the airflow to my experiments. The range of air velocities that I need is 2m/s to 20m/s. A source of airflow (I think it will be an air blower) will need to be powerful enough to overcome some significant resistances, given to the airflow by physical...

    Selection of anemometer and pressure differential measure device for air tunnel

    Dear All, I develop a lab air tunnel in order to measure pressure drops before and after a wall of little pills. I send attached the concept of tunnel. 1. I search online stores looking for an optimum anemometer/pitot tube in terms of cost/quality. Expected range of velocities to be measured...

    Porous zone - setup of lab air tunnel - velocity v's pressure drop

    Dear All, I have developed a 3D model of airflow through: inlet air zone – porous zone – outlet air zone. Porous media represents a large number of pills. In a real process, the air is pumped among these pills. The viscous and inertial resistances of the porous zone have been calculated based...

    CAD softare - auto pack/nesting of 3D models in 3D volume

    Hi All, I am looking for a CAD software which would have a feature of auto packing 3D objects in a specific 3D volume. More specifically, I have a 3D CAD box 100mmx100mmx100mm. I have also 3D CAD model of a product i.e. 13mmx13mmx9mm (with rounded edges). I need to fill 3D CAD box...

    Porous media - air zone interface

    Dear All, I prepare a model for 2D airflow analysis in Fluent. Air flows through inlet -> air zone -> porous media -> air zone -> outlet I am not sure whether I should define somehow the interface between porous media and 'air zone'. Also I have another question related to selection of...

    3D simulation of airflow through small objects

    Hi, I model in Ansys Fluent a scenario where the air flows through a bunch of little balls. I send a drawing. The air is delivered to the container (through a single inlet) that is filled with little balls, as per the attached drawing. Once the air comes out from the inlet, the majority of air...

    Simulation of the airflow through a bunch of little balls

    Dear All, I hope you are well. I start my work with Ansys Fluent (I did a few airflow analyses long time ago). I need to model the airflow through a bunch of little balls (see attached draft and picture on it, these balls are for illustration only, the actual balls look somewhat different)...

    Teflon coating of the immersion heater (12V 600W)

    Hi, I need to teflon coat the heating element (made from stainless steel) of the immersion heater. I have came across many techniques in the internet of Teflon coating. Could anyone point on the simplest method of the in house teflon coating? Please help Regards

    Brass bar hard coating

    Hi, I have the brass component (overall size 50mmx50mm1000mm). Brass is CZ121. This brass component has hundreds of through holes of diameter 0.3mm each and 2.4mm deep. I need to cover this brass component with hard and low-abrasive protective coating (thickness approx. 10microns) that has...

    Brass shrinkage

    Hi, I would like to ask a question about the brass shrinkage (CZ121). I have a brass component in the machine (approx. 50mmx50mmx1000mm) which experiences shrinkage over the course of its life-time (approx. 2-2.5mm on its longest side). The brass component, once fixed in the machine is...

    Equipment for high air velocity and temperature measure

    Hi, I am looking for the measure equipment for the melt blowing process parameters. I am interested in the tooling which would allow to measure the air velocity and temperature. The assumed maximum velocity of the air would be approximately 250m/s and the air maximum temperature is assumed...

    Best technology for micro holes machining

    Hi, I am looking for the best technology of making a long array of through holes (0.2mm diameter) in two metals (stainless steel and brass). Pitch is 0.4mm. Those holes are to be made in the spray head which comes from the molten fiber flow machine. Best technologies identified so far are...
