DSIR-recognised R&D centre

R&D, CFD & Prototyping

Computational Fluid Dynamics, rapid prototyping and physical testing — so the mesh is chosen on evidence before you commit to tooling and volume.

Flow Modelled First

CFD analysis of flow within the mesh structure.

Prototype Early

Rapid samples before tooling commitment.

Government Recognised

DSIR-recognised in-house R&D centre.

Joint Programmes

R&D collaboration with the Government of India.

Overview

Choose the right mesh before you scale

Through its committed research and development work, BVK has been able to secure its technological edge. We use Computational Fluid Dynamics and rapid prototyping to analyse flow dynamics within the mesh structure — which means the trade-off between porosity, pressure drop and strength can be examined on screen and on a sample bench, rather than discovered after the first production batch.

Development path

Five steps to a frozen specification

The point of this sequence is to move the expensive discoveries to the front, where they are still cheap.

  1. Step 01

    Define Conditions

    Operating envelope, medium, chemistry and constraints.

  2. Step 02

    Model Options

    CFD and simulation across candidate structures.

  3. Step 03

    Build Prototypes

    Rapid samples of the shortlisted geometries.

  4. Step 04

    Test & Tune

    Physical testing against agreed norms, then refine.

  5. Step 05

    Release Route

    Control plan, PPA and production specification frozen.

Why develop with BVK

Engineering input, not order taking

Filtration and electrochemical mesh are rarely plug-and-play; they require close cooperation between supplier and customer. BVK is resourced for that cooperation rather than for catalogue fulfilment.

Recognised Laboratory

In-house R&D recognised by the Government of India through DSIR.

Simulation Capability

CFD and digital twin modelling applied before any tooling is cut.

Joint R&D Programmes

Collaboration with the Government of India.

Development to Volume

The same organisation that prototypes it also produces it at scale.

Sustainability

Powering a cleaner planet

Woven and knitted mesh support electrolysers and fuel cells across the green hydrogen value chain. BVK also powers 50%+ of its energy needs through renewables, with a goal of becoming 100% self-reliant.

Let's build a cleaner tomorrow

Have a mesh problem that is not solved yet?

Bring it early. The cheapest time to find out that a structure will not work is before the tooling exists — and that is exactly what CFD and prototyping are for.
